Hi, I have a simple desire. I have a string that I need to parse as a date/time string in the local timezone, then convert it to standard seconds-since-epoch format. This is trivial in C, Perl, Python, etc. but seems impossible to do reliably in Haskell. I'm hoping someone can tell me where I've gone wrong. My initial idea was to parse the string, generate a CalendarTime object, use toClockTime to convert it to seconds-since-epoch, and then grab the value out of that. There were some problems, though: what to put in ctTZ and ctIsDST? I initially loaded them with 0 and False, though that turned out to be clearly wrong. My next idea was to take the ctTZ result from toCalendarTime, then use that for all the CalendarTime objects I'd generate. That was wrong, too, during daylight savings time. I don't think I should have to re-implement the algorithms for determining whether a given date is under DST worldwide. What I really need is just a wrapper around mktime() that just calls mktime and doesn't do anything else. All the post-processing that System.Time is doing is what's causing me trouble. I'd just like it to ignore ctTZ, ctTZName, and ctIsDST. That would yield behavior identical to the C library. -- John
