Support "of", "tzh", and "tzm" format codes.

Browse Source 
The upper case versions "OF", "TZH", and "TZM" are already supported,
and all other format codes that are supported in upper case are also
supported in lower case, so we should support these as well for
consistency.

Nitin Jadhav, with a tiny cosmetic change by me. Reviewed by Suraj
Kharage and David Zhang.
