Python RFC 3339 implementation
Implementation of the majority of
http://www.ietf.org/rfc/rfc3339.txt. Provides an implementation of
tzinfo for UTC (why isn't this in the standard library?) as well as
various parsing and formatting routines based on RFC 3339's syntax for
dates and times.
Use datetime.datetime.isoformat() as an inverse of the various parsing routines in this module.
This library sticks quite closely to the RFC 3339 profile of ISO
8601. If that's too strict for you, and you need something for parsing
more general ISO 8601 dates and times, you might find
pyiso8601 (in debian as package
Examples and documentation
See the docstrings in the rfc3339 module source code itself.
Limitations and potential improvements
Limitations, with respect to RFC 3339:
Section 4.3, "Unknown Local Offset Convention", is not implemented.
Section 5.6, "Internet Date/Time Format", is the ONLY supported format implemented by the various parsers in this module. (Section 5.6 is reproduced in its entirety below.)
Section 5.7, "Restrictions", is left to the datetime.datetime constructor to implement, with the exception of limits on timezone minutes-east-of-UTC magnitude. In particular, leap seconds are not addressed by this module. (And it appears that they are not supported by datetime, either.)
- Support for leap seconds. (There's a table of them in RFC 3339 itself, and http://www.nist.gov/pml/div688/grp50/leapsecond.cfm <!-- used to be http://tf.nist.gov/pubs/bulletin/leapsecond.htm --> is supposed to update monthly.)
