1. Fixed a bug in db_prepare_date()
2. Added db_prepare_double()
3. Fixed several other time tracking related issues.
4. Fixed the from/to in the queries.
5. Changed the APIs to follow Mantis coding style and variable cleanup guidelines.
6. Default the time tracking edit box in the bug note form to 00:00. This was done only when javascript is turned off.

Probably several other things.
