No apologies needed bud. None of us are getting paid to do this you know ;\)

I think AutoIT can do it though...

 Code:
; #FUNCTION# ====================================================================================================================
; Name...........: _Date_Time_SetTimeZoneInformation
; Description ...: Sets the current time zone settings
; Syntax.........: _Date_Time_SetTimeZoneInformation($iBias, $sStdName, $tStdDate, $iStdBias, $sDayName, $tDayDate, $iDayBias)
; Parameters ....: $iBias       - The current bias for local time translation on this computer.  The bias is the difference in
;                  +minutes between Coordinated Universal Time (UTC) and local time.  All translations between UTC and local time
;                  +use the following formula: UTC = local time + bias
;                  $sStdName    - The description for standard time
;                  $tStdDate    - A %tagSYSTEMTIME structure that contains a date and local time when the transition from
;                  +daylight saving time to standard time occurs.
;                  $iStdBias    - The bias value to be used during local time translations that occur during standard time.  This
;                  +value is added to the value of the Bias to form the bias used during standard time.  In most time zones, this
;                  +value is zero.
;                  $sDayName    - The description for daylight saving time
;                  $tDayDate    - A %tagSYSTEMTIME structure that contains a date and local time when the transition from
;                  +standard time to daylight saving time occurs.
;                  $iDayBias    - The bias value to be used during local time translation that occur during daylight saving time.
;                  +This value is added to the value of the Bias member to form the bias used during daylight saving time.  In
;                  +most time zones this value is –60.
; Return values .: Success      - True
;                  Failure      - False

Maybe? If so, it just another time when I absolutely hate it when our "competition" can do something we can't.
