- CLASSES:
- LocaleTime -- Discovers and stores locale-specific time information
- TimeRE -- Creates regexes for pattern matching a string of text containing
- time information
-
- FUNCTIONS:
- _getlang -- Figure out what language is being used for the locale
- strptime -- Calculates the time struct represented by the passed-in string

- The locale language is set at the offset and then checked again before
- exiting. This is to make sure that the attributes were not set with a
- mix of information from more than one locale. This would most likely
- happen when using threads where one thread calls a locale-dependent
- function while another thread changes the locale while the function in
- the other thread is still running. Proper coding would call for
- locks to prevent changing the locale while locale-dependent code is
- running. The check here is done in case someone does not think about
- doing this.
-
- Only other possible issue is if someone changed the timezone and did
- not call tz.tzset . That is an issue for the programmer, though,
- since changing the timezone is worthless without that call.
