DatetimeToUnix is defined as returning the "Unix epoch time  
corresponding to AValue". So by definition it does not perform any  
time zone adjustments (which is logical, since there is no information  
regarding what time zone the input value is related to). It's the same  
in Delphi (just google for DatetimeToUnix+timezone

If you want "now" using the local time zone, use sysutils.getlocaltime  
instead.
