GMT == UTC, yes? Did you mean converting local times to GMT/UTC, or were you meaning UNIX epoch time when you wrote "UTC"? Either way, I recommend you try the too-little-known "convdate" utility, which should be on most UNIX systems because it's a part of the INN distribution. convdate -n will take a string with a date/time and output the corresponding UNIX time. "man convdate" for more info and some illuminating examples. -- Clifton -- Clifton Royston -- LavaNet Systems Architect -- [EMAIL PROTECTED] WWJD?
