I am using Virtaal to create en_US translatation, and after going through the .po file, there are certain date strings that are still not being translated in the front end. Specifically:
15.08.2012 08:15 - (now!) the date range under Monitoring - Graphs - Filter - Zoom box date ranges in top right corner:
2012.Aug.15 09:14:51 in timestamp under Monitoring - Latetst data - ... - Values
10 Aug 2012 time values under Monitoring - Events - Trigger (Time Column)
I am planning on uploading the file to pootle as soon as I get proper permissions.
