Do you wan to convert the string "&raquo; Thu Oct 06, 2005 6:24 pm </p>" into string "2005-10-06 18:24:00" ?
You said you could do it with Xbase++.
Can you please share your XBase++ code that does this conversion?

Yes

there is not special Xbase++ Function to convert that String into Date/Time Format

i have made a ""Quick & Dirty" Function to convert
Code: Select all  Expand view
FUNCTION StringDate( cLine, cTime )
LOCAL ii, nPosi, cMonth, cNext, cYear, nSec, cMore
LOCAL cYYYY, cMM, cDD, cHHMMSS
LOCAL aMonth := { "Jan", ;
                     "Feb", ;
                     "Mar", ;
                     "Apr", ;
                     "May", ;
                     "Jun", ;
                     "Jul", ;
                     "Aug", ;
                     "Sep", ;
                     "Oct", ;
                     "Nov", ;
                     "Dec" }

   cTime := "00:00:00"

   FOR ii := 1 TO LEN( aMonth )
      IF aMonth[ ii ] $ cLine
         cMM := STRZERO( ii, 2 )
         cMonth := aMonth[ ii ]
         EXIT
      ENDIF
   NEXT
   IF EMPTY( cMM )
      RETURN CTOD( " . . " )
   ENDIF

   nPosi := AT( "&raquo;", cLine )
   IF nPosi > 0
      cLine := SUBSTR( cLine, nPosi + 7 )
   ELSE
      RETURN CTOD( " . . " )
   ENDIF

   //  &raquo; Thu Oct 06, 2005 6:24 pm </p>
   nPosi := AT( cMonth, cLine )
   IF nPosi > 0
      cNext := SUBSTR( cLine, nPosi + 3 )

      nPosi := AT( ",", cNext )
      IF nPosi > 0
         cDD := LTRIM( SUBSTR( cNext, 1, nPosi - 1 ) )

         cYear := LTRIM( SUBSTR( cNext, nPosi + 1 ) )
         cYYYY := SUBSTR( cYear, 1, 4 )

         cMore := SUBSTR( cYear, 5 )
         IF "pm" $ cMore
            nPosi := AT( "pm", cMore )
            cHHMMSS := SUBSTR( cMore, 1, nPosi - 1 )
            nSec := HMS2SEC( cHHMMSS )
            nSec += ( 12 * 60 * 60 )
            cHHMMSS := SEC2HMS( nSec )
         ELSE
            nPosi := AT( "am", cMore )
            cHHMMSS := SUBSTR( cMore, 1, nPosi - 1 )
            nSec := HMS2SEC( cHHMMSS )
            cHHMMSS := SEC2HMS( nSec )
         ENDIF

      ELSE
         RETURN CTOD( " . . " )
      ENDIF
   ELSE
      RETURN CTOD( " . . " )
   ENDIF

   cTime := cHHMMSS

RETURN STOD( cYYYY + cMM + cDD )

p.s.
HMS2SEC() and SEC2HMS() are to convert HH:MM:SS <-> Seconds
is there a harbour Function :?:

Not sure this is useful to anybody to me, but this is how I convert back and forth from harbour datetime to ISO datetime.

Code: Select all  Expand view

// -------------------------------------------------------------------------- //

// DateTimeToISO8601( t )
FUNCTION hb_TToI( t )

   hb_Default( @t, DateTime() )
   t := hb_TToS( t )
   RETURN SubStr( t, 01, 04 ) + "-" + ;
          SubStr( t, 05, 02 ) + "-" + ;
          SubStr( t, 07, 02 ) + "T" + ;
          SubStr( t, 09, 02 ) + ":" + ;
          SubStr( t, 11, 02 ) + ":" + ;
          SubStr( t, 13, 02 ) + "." + ;
          SubStr( t, 15, 03 )

// -------------------------------------------------------------------------- //

// IS8601ToDateTime
FUNCTION hb_IToT( cISO )

   IF Empty( cISO )
      RETURN _EMPTY_DATETIME
   ENDIF

   RETURN hb_DateTime( Val( SubStr( cISO, 01, 04 ) ), ;
                       Val( SubStr( cISO, 06, 02 ) ), ;
                       Val( SubStr( cISO, 09, 02 ) ), ;
                       Val( SubStr( cISO, 12, 02 ) ), ;
                       Val( SubStr( cISO, 15, 02 ) ), ;
                       Val( SubStr( cISO, 18, 02 ) ), ;
                       Val( SubStr( cISO, 21, 03 ) ) )

Code: Select all  Expand view
Secs( <cTimeStr> / <tDateTime> ) --> nSecs
TimeToSec( <cTimeStr> ) --> nSecs


TString( nSecs ) --> cTimeStr
SecToTime( [<nSeconds>], [<lHundredth>] ) --> cTime

Thanks Rao. The secs() function in harbour actually gets mapped to hb_sec() in dateshb.c, which took me a few minutes to find. But I see a bunch of potentially useful functions there now that I'm going to test to see if I can get rid of the code I'm currently using and revert to native harbour.

I think these functions can be simplified like this:
Code: Select all  Expand view
function ISO2DateTime( cDate )

   local df          := Set( _SET_DATEFORMAT, "YYYY-MM-DD" )
   local tf          := Set( _SET_TIMEFORMAT, "HH:MM:SS.fff" )
   local tDateTime   := HB_CTOT( cDate )

   Set( _SET_DATEFORMAT, df )
   Set( _SET_TIMEFORMAT, tf )

return tDateTime

function DateTime2ISO( tDateTime )

   local df          := Set( _SET_DATEFORMAT, "YYYY-MM-DD" )
   local tf          := Set( _SET_TIMEFORMAT, "HH:MM:SS.fff" )
   local cDate       := StrTran( HB_TTOC( tDateTime ), " ", "T" )

   Set( _SET_DATEFORMAT, df )
   Set( _SET_TIMEFORMAT, tf )

return cDate
 
All times are UTC
