[RFC PATCH 0/2] natural language date range search

[Jani Nikula <jani@nikula.org>]

Hi all, these patches add support for natural language date range search
of the form date:since..until, where since and until can be fairly free
form date/time expressions in English.

Examples:

date:two-days..yesterday (all mail in the two days before today)
date:12h.. (all mail since 12 hrs ago)
date:november..november (all mail in previous november)
date:2011.. (all mail since the beginning of 2011)
date:last-week..this-week (all mail over last and current week)
date:5/10/2011-12:34:55..10pm_2012-01-14

Plus plenty more and combinations of the above.

The repository for the date/time parser with a command line tool is at
[1], and there's a README [2] with a bunch of details too.


BR,
Jani.
