* harbour/bin/hb-func.sh
    ! restored default optimization flag (-O3) in hb* scripts

  * harbour/harbour.spec
    ! fixed recent modification

  * harbour/contrib/rddads/ads1.c
  * harbour/contrib/rddads/adsfunc.c
  * harbour/contrib/hbmisc/strfmt.c
  * harbour/contrib/hbcrypt/sha1.c
    ! fixed wrongly used C reference operator

  * harbour/contrib/hbwin/win_prn2.c
  * harbour/contrib/hbwin/wapi_commctrl.c
  * harbour/source/vm/maindllp.c
    ! fixes for unicode builds

  * harbour/include/std.ch
    + added SET TIME FORMAT [TO] <f>

  * harbour/include/set.ch
  * harbour/include/hbset.h
  * harbour/source/vm/set.c
    + added _SET_TIMEFORMAT
      The folowing modifiers are supported:
         hh - hours
         mm - minutes
         ss - seconds
         fff - fraction part of seconds
         p - 1-st letter from PM / AM signature. When used time is shown
             in 12 hour format otherwise 24 hour format is used
      ex: Set( __SET_TIMEFORMAT, "hh:mm pm" )
      default _SET_TIMEFORMAT value is "hh:mm:ss:fff"
    + added C function: char * hb_setGetTimeFormat( void );

  * harbour/include/hbpp.h
  * harbour/source/pp/ppcore.c
    + added support for timestamp constant values in the form:
         t"YYYY-MM-DD HH:MM:SS.fff"
      The exact accepted timestamp pattern is is:
         YYYY-MM-DD [H[H][:M[M][:S[S][.f[f[f[f]]]]]]] [PM|AM]
      i.e.:
         tValue := t"2009-03-21 5:31:45.437 PM"
      or:
         YYYY-MM-DDT[H[H][:M[M][:S[S][.f[f[f[f]]]]]]] [PM|AM]
      with literal "T" as date and time part delimiters (XML timestamp
      format), i.e.:
         tValue := t"2009-03-21T17:31:45.437"
      The folowing characters can be used as date delimiters: "-", "/", "."
      if PM or AM is used HH is in range < 1 : 12 > otherwise
      in range < 0 : 23 >

  * harbour/source/compiler/complex.c
  * harbour/source/compiler/harbour.y
  * harbour/source/compiler/harbour.yyc
  * harbour/source/compiler/harbour.yyh
    + added support for t"YYYY-MM-DD HH:MM:SS.fff" time stamp constant
      to compiler
    + added support for VFP datetime constant values:
         { ^ [ YYYY-MM-DD [,] ] [ HH[:MM[:SS][.FFF]] [AM|PM] ] }
      The following characters can be used as date delimiters: "-", "/".
      Dot "." as date delimiter is not supported.
      There is no limit on number of characters in YYYY, MM, DD, HH, MM,
      SS, FFF parts. Important is only their value. This is the format
      in semi PP notation:
         { ^ <YEAR> <sep:/-> <MONTH> <sep:/-> <DAY> [[<sep2:,>]
           [ <HOUR> [ : <MIN> [ : <SEC> [ . <FRAQ> ] ] ] [AM|PP] ] }
      In practice it allows to also parse xHarbour datetime constant
      values with compatible conditions though xHarbour support onlu "/"
      as date delimiter.
      NOTE: there is one important difference to VFP and xHarbour in
      decoding above format. In VFP and xHarbour when date part is
      missing then it's set by default to: 1899-12-30 so this code:
         { ^ 12:00 }
      gived the same results as:
         { ^ 1899/12/30 12:00 }
      Harbour does not set any default date value when timestamp
      constant value contains only time part.
      If you want we can change it for strict VFP compatiblity.
      Now this extension is enabled by default for testing. In the future
      it will be probably covered by HB_COMPAT_FOXPRO macro.

      BOOL hb_arraySetTD( PHB_ITEM pArray, ULONG ulIndex, double dTimeStamp )
      BOOL hb_arrayGetTDT( PHB_ITEM pArray, ULONG ulIndex,
                           LONG * plJulian, LONG * plMilliSec );
      BOOL hb_arraySetTDT( PHB_ITEM pArray, ULONG ulIndex,
                           LONG lJulian, LONG lMilliSec );

  * harbour/include/hbapi.h

  * harbour/source/vm/hvm.c
    + added HB_IT_TIMESTAMP items
    * modified HB_IT_DATE internal item structure to use common structure

    + added HB_IS_DATETIME() and ISDATETIME() macros - they return true
      if item/parameter is DATE or TIMESTAMP type.

      and xhb_vmPushTimeStamp()
    + added support for timestamp values in relational operators:
         <, <=, >, >=, =, ==
      When two timestamp values are compared then VM compares date and
      time parts in both values.
      When date and timestamp values are used in <, <=, >, >=, = operations
      then VM compares only date part in both values.
      When date and timestamp values are used in == operation then VM
      compares date part in both values and then check if time part
      of timestamp value is 0.
    + added support for timestamp values in + and - math operations.
      The following rules are used in timestamp arithmetic:
         <t> + <t> => <t>
         <t> - <t> => <n>
         <t> + <n> => <t>
         <n> + <t> => <t>
         <t> - <n> => <t>
         <d> + <t> => <t>
         <t> + <d> => <t>
         <d> - <t> => <n>
         <t> - <d> => <n>
      When number is result or argument of timestamp operation then the
      its integer part is a number of day and fractional part is the time.

  * harbour/source/rtl/dateshb.c
    + added new .prg functions to mange date and timestamp values:
      HB_DATETIME() -> <tTimeStamp>
      HB_CTOD( <cDate> [, <cDateFormat> ] ) -> <dDate>
      HB_DTOC( <dDate> [, <cDateFormat> ] ) -> <cDate>
      HB_NTOT( <nValue> ) -> <tTimeStamp>
      HB_TTON( <tTimeStamp> ) -> <nValue>
      HB_TTOC( <tTimeStamp>, [ <cDateFormat> ] [, <cTimeFormat> ] ) ->
                                                            <cTimeStamp>
      HB_CTOT( <cTimeStamp>, [ <cDateFormat> ] [, <cTimeFormat> ] ) ->
                                                            <tTimeStamp>
      HB_TTOS( <tTimeStamp> ) -> <cYYYYMMDDHHMMSSFFF>
      HB_STOT( <cDateTime> ) -> <tTimeStamp>
         <cDateTime> should be in one of the above form:
            - "YYYYMMDDHHMMSSFFF"
            - "YYYYMMDDHHMMSSFF"
            - "YYYYMMDDHHMMSSF"
            - "YYYYMMDDHHMMSS"
            - "YYYYMMDDHHMM"
            - "YYYYMMDDHH"
            - "YYYYMMDD"
            - "HHMMSSFFF"
            - "HHMMSSF"
            - "HHMMSS"
            - "HHMM"
            - "HH"
         Important is number of digits.
      HB_TSTOSTR( <tTimeStamp> ) -> <cTimeStamp> // YYYY-MM-DD HH:MM:SS.fff
      HB_STRTOTS( <cTimeStamp> ) -> <tTimeStamp>
         <cTimeStamp> should be in one of the above form:
            YYYY-MM-DD [H[H][:M[M][:S[S][.f[f[f[f]]]]]]] [PM|AM]
            YYYY-MM-DDT[H[H][:M[M][:S[S][.f[f[f[f]]]]]]] [PM|AM]
         The folowing characters can be used as date delimiters: "-", "/", "."
         T - is literal "T" - it's for XML timestamp format
         if PM or AM is used HH is in range < 1 : 12 > otherwise
         in range < 0 : 23 >
      HB_HOUR( <tTimeStamp> ) -> <nHour>
      HB_MINUTE( <tTimeStamp> ) -> <nMinute>
      HB_SEC( <tTimeStamp> ) -> <nSeconds>   // with milliseconds

  * harbour/source/rtl/minmax.c
    + added support for timestamp values to MIN() and MAX() functions.
      when only one of given parameters is timestamp value and other
      is date value and date parts are equal then always date item
      is returned as both MIN() or MAX() value.

  * harbour/source/rtl/dates.c
    + added new C functions: hb_timeFormat(), hb_timeUnformat(),
      hb_timeStampFormat(), hb_timeStampUnformat()

  * harbour/source/rtl/valtype.c
    + added .prg functions: HB_ISDATETIME(), HB_ISTIMESTAMP()

  * harbour/source/rtl/transfrm.c
    + added support for timestamp items formatting.
    + added new function modifier @T.
      When @T is used without @D then only time part of timestamp value
      is formatted and return.
      When @D is used without @T then only date part of timestamp value
      is formatted and return.

  * harbour/source/rtl/tbrowse.prg
    + display timestamp values

  * harbour/source/rtl/philes.c
    + accept timestamp value as second parameter of HB_FSETDATETIME()
      function
    + store file data and time in second parameter of HB_FGETDATETIME()
      as timestamp value.
    Old parameters (2-dDate, 3-cTime) are still supported but please think
    about removing them - they are redundant.

  * harbour/source/rtl/filesys.c
    * updated function names


  * harbour/source/rdd/dbf1.c

  * harbour/source/rdd/dbfnsx/dbfnsx1.c
  * harbour/source/rdd/dbffpt/dbffpt1.c
    + added support for indexing timestamp fields
    + added support for using DATE values with timestamp fields
      which replicate HVM behavior.
      SEEK and SEEKLAST with date value when active index is on
      timestamp positions to 1-st or last record where date part
      of indexed timesamp value is equal.
      Settings scopes to date values when active index is on timestamp
      value reduce the visible record range to these ones which have
      date part of timestamp value in the range of dates values used
      for scopes. It possible to mix date and timestamp values in scope
      and set one scope to date value and the second to timesamp.

  * harbour/source/rdd/sdf1.c
  * harbour/source/rdd/delim1.c
    + added support for exporting timestamp fields

  * harbour/source/rdd/dbsql.c
    ! fixed typo in logical value export
    + export timestamp fields.
      Please update the format to given SQL syntax.


  * harbour/contrib/hbct/files.c
    + changed SETFDATI() to optionally accept timestamp parameter
      instead of two parameters dDate and cTime

  * harbour/contrib/hbct/misc1.c
    + added timestamp support to XTOC() function

  * harbour/contrib/hbct/misc2.c
    + added timestamp support to COMPLEMENT() function

      LASTDAYOM(), WEEK() functions

  * harbour/contrib/hbmzip/hbmzip.c
    + updated HB_ZipFileCreate( hZip, cZipName, tDateTime, cTime, ... )
      functions to optionaly accept timestamp value in 3-rd parameter
      instead od dDate, and cTime in 3-rd and 4-th parameters.
    + updated HB_UnzipFileInfo( hUnzip, @cZipName, @tDateTime, @cTime, ... )
      to return timestamp value in 3-rd parameter instead of date value.
      TODO: Please think about removing 4-th parameter from:
               HB_ZipFileCreate( hZip, cZipName, tDateTime, cTime, ... )
               HB_UnzipFileInfo( hUnzip, @cZipName, @tDateTime, @cTime, ... )
            Now it's redundant.
  * harbour/contrib/hbmzip/readme.txt
    * updated parameters description for above functions

  * harbour/contrib/hbnf/descendn.c
    + added timestamp support to FT_DESCEND() function

  * harbour/contrib/hbclipsm/date.c
    + accept timestamp values in DATEASAGE(), DATEASARRAY() and DATEISLEAP()

      WOM(), WOY(), EOY() and BOY() functions


   The following contrib files should be updated but I'm leaving it to
   other developers who want to keep this code alive:
         contrib/hbtip/utils.c
         contrib/hbvpdf/hbvpdf.prg
         contrib/hbvpdf/hbvpdft.prg
         contrib/hbwin/win_dll.c
            some minor cleanups if necessary and authors will find
            timestamp values usable

         contrib/hbole/ole2.c
         contrib/hbwin/win_ole.c
            add support for timestamp values in OLE

         contrib/rddado/adordd.prg
         contrib/rddads/ads1.c
         contrib/rddads/adsx.c
         contrib/rddsql/...
            add support for timestamp values in RDDs

   Warning: this implementation is not xHarbour compatible. There are many
   important differences. Mostly on C level and used API. Please be careful
   in porting xHarbour source code to Harbour.
