Hi, list

How with python standard library to convert string like 'YYYY-MM-DD
mm:HH:SS ZONE' to seconds since epoch in UTC? ZONE may be literal time
zone or given in explicit way like +0100.

If you have a sufficiently recent version of Python, have you considered time.strptime: http://docs.python.org/library/time.html#time.strptime ?

HTH,

Yes. May be I don't undertand something. but it seems strptime doesn't
work with timezones at all. Only understands localzone and dates w/o zones.

Given the documentation talks about "double leap seconds" which don't
exist, why should this code be trusted?

Because they exist(ed) in POSIX. See
http://www.ucolick.org/~sla/leapsecs/onlinebib.html :
"""
The standards committees decided that POSIX time should be UTC, but
the early POSIX standards inexplicably incorporated a concept which
never existed in UTC -- the ``double leap second''. This mistake
reportedly existed in the POSIX standard from 1989, and it persisted
in POSIX until at least 1997.
