It would be nice if you could somehow provide a link in your time log entry back to a revision in the SCM. Most of the time (on dev projects), time is updated when code is checked in. You can provide a link to the task in question in the commit log, but you can't link back when recording your time.

Basically just something along the lines of "See Commit X", where X is rendered as a link back to the SCM for the project the task belongs to.
