time information

LocaleTimeak Stores and handles locale-specific information related to time.
ATTRIBUTES:
f_weekday -- full weekday names (7-item list)
a_weekday -- abbreviated weekday names (7-item list)
f_month -- full month names (13-item list; dummy value in [0], which
is added by code)
a_month -- abbreviated month names (13-item list, dummy value in
[0], which is added by code)
am_pm -- AM/PM representation (2-item list)
LC_date_time -- format string for date/time representation (string)
LC_date -- format string for date representation (string)
LC_time -- format string for time representation (string)
timezone -- daylight- and non-daylight-savings timezone representation
(2-item list of sets)
lang -- Language used by instance (2-item tuple)

krdtd��dS )a� Set all attributes.
Order of methods called matters for dependency reasons.
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.
