This indicates a real bug, though your precise wording is incorrect. The real problem is that timezone is the opposite sign than it ought to be, and the fix is simply to negate it (always .. not just when it would otherwise be negative), in zones east of Greenwich, "timezone" should in fact be negative (and the application still subtracts its value from the current time). Its probably indicative of just how little used this variable is incidentally, that this bug wasn't noticed before! If there was ever good evidence to simply kill "timezone" then I think this is it! I would also be interested in exactly what application that you have that uses this variable. Does it use it correctly? Simply subtracting it from a time isn't correct, as that won't work in daylight saving times. About all I can think of is that you look at tm_isdst and if that's set compensate by 1 hour (assuming that it is, always, one hour). I don't think the other fixes are appropriate at the minute, but this one will get into a patch posted to mod.sources. Robert Elz
