+Hi all, these patches add support for natural language date range search\r
+of the form date:since..until, where since and until can be fairly free\r
+form date/time expressions in English.\r
+\r
+Examples:\r
+\r
+date:two-days..yesterday (all mail in the two days before today)\r
+date:12h.. (all mail since 12 hrs ago)\r
+date:november..november (all mail in previous november)\r
+date:2011.. (all mail since the beginning of 2011)\r
+date:last-week..this-week (all mail over last and current week)\r
+date:5/10/2011-12:34:55..10pm_2012-01-14\r
+\r
+Plus plenty more and combinations of the above.\r
+\r
+The repository for the date/time parser with a command line tool is at\r
+[1], and there's a README [2] with a bunch of details too.\r
