[...]
* Parses date/time string values in an almost seamless way.
* Provides conversion routines to and from many different alternative
date/time storage formats.
* Includes an easy-to-use C API which makes integration a breeze.
* Fast, memory efficient, accurate.
* Georgian and Julian calendar support.
* Vast range of valid dates (including B.C. dates).
* Compatible to Python's datetime and time modules.
* Stable, robust and portable (mxDateTime has been around for almost 10
years now).
* Free to use and redistribute.
* Fully interoperates with Python's time and datetime modules.

Summary: OAIRepository: handle dates before 1900-01-01
Project: CDS Invenio
Submitted by: jcaffaro
Submitted on: 2009-10-22 05:40
Should Start On: 2009-10-22 00:00
Should be Finished on: 2009-10-22 00:00
Category: BibHarvest
Priority: 5 - Normal
Status: None
Privacy: Public
Percent Complete: 0%
Assigned to: None
Open/Closed: Open
Discussion Lock: Any
Effort: 0.00
_______________________________________________________
The OAI gateway does not support dates prior to 1900, due to usage of the
_time_ module.
Solutions to explore:
* Use built-in _datetime_ module (be cautious since _datetime.strftime()_
still does not support years prior to 1900)
* Use python-dateutil module
* Do not accept dates prior to 1900 as input (at least returns an
OAI-compliant output)
