They are completly useless and error prone as they only consider the "just now" situation, so any other GMT/UTC time different than now could be wrongly converted and apparently be ok. Example, you record a time today 21 sept. 2010, in my local time (CET-1CEST) there is an offset of +2 hours from GMT, you can go GMT to local and back succesfully up to the last sunday of october where DST is not applied anymore up to the next year. So any conversion done in november over thet data recorded the 21 sept. 2010 will be converted with an offset of +1 (november) instead the +2 offset (when the time was recorded). To solve this you need PascalTZ or similar functions. -- Best regards, José -- _______________________________________________ Lazarus mailing list [email protected] http://lists.lazarus.freepascal.org/mailman/listinfo/lazarus
