Registration traceback

[Greg Couch]

At the beginning of #3123 is a traceback in the Registration bundle. strptime fails to parse the date string. This might be caused by the %a and %b specifiers, since they are locale dependent. Recommendation would be to put a context manager around uses of strftime and strptime that would set the locale to an English variation writing and parsing dates, as appropriate.

Fixed in [changset:1a20a02de].

Temporarily set locale to en_us when parsing registration timestamps.
