These are understood by the find's date parser (the same one as used
in GNU date) as being in timezone 'Tango' which is abbreviated 't'
(see 
http://www.timeanddate.com/library/abbreviations/timezones/military/t.html).

Compare for example:

$ date -u  -d '2012-11-15t00:29'
Wed Nov 14 17:29:00 UTC 2012

If you want to specify T as a separator between the date and the time,
per ISO801, you need to use an upper-case "T".   For more details,
please refer to
<http://en.wikipedia.org/wiki/ISO_8601#Combined_date_and_time_representations>.

Thanks,
