Yes, that is the ISO 8601 format, and the only sane format you should use. Even in my database application, my dates are stored as text fields using the ISO 8601 date/time format, instead of db server Timestamp fields (which could cause confusion too, depending on server locale settings). > Is this ISO 8601 format currently the most widely used?

In the tiOPF project I created a couple of methods (and unit tested them) to do conversion between string format and TDateTime format. You are welcome to use them for your purpose. ----------------[ Core/tiUtils.pas ]-------------------- function tiDateTimeAsIntlDateStor(const ADateTime: TDateTime): string; function tiDateTimeAsIntlDateDisp(const ADateTime: TDateTime): string; function tiDateAsIntlDateDisp(const ADateTime: TDateTime): string; function tiIntlDateStorAsDateTime(const AValue: string): TDateTime; function tiIntlDateDispAsDateTime(const AValue: string): TDateTime; ---------------------------------------- Code can be found here... http://tiopf.svn.sourceforge.net/viewvc/tiopf/tiOPF2/Trunk/Core/tiUtils.pas?view=markup Also, here is a summary of ISO 8601: http://www.cl.cam.ac.uk/~mgk25/iso-time.html Regards, - Graeme - -- fpGUI Toolkit - a cross-platform GUI toolkit using Free Pascal http://fpgui.sourceforge.net/ _______________________________________________ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-pascal
