- timegm() is a GNU function that might not be available everywhere.
- It's basically the inverse of gmtime() - you give it a struct tm,
- and get back a time_t. It differs from mktime() in that it handles
- the case where the struct tm is UTC and the local environment isn't.
-
- Note, that this replacement implementation might not be thread-safe!
-
- Some BSDs don't handle the putenv("foo") case properly, so we use
- unsetenv if the platform has it to remove environment variables.
