non standard datetime library.Date parsing.

[anonymous]

Hi!
My current task included date parsing and recognizing.
It's not enough hard but there are some problems.

A lot of standards of date exists at this time:
ISO,ARPA...+non standard date strings.
And the main problem is timezone - strings which I should parse can include nonstandard timezone name like ET instead of EDT or EST.

Does anyone know module or library which can identify timezone in this format.

Now I use mxDateTime
but it's not enough universal.

Who knows better?
