Align timestamps in Time Control

[ghost]

Timestamps should be aligned in the Time Control widget when the shown formats are different (since the "project range" text fields always show the full date + timezone). For example, right now it shows:

                  11:24:45.797427712
2012-03-19 11:24:42.440133097 -04:00

but it should be aligned as:

           11:24:45.797427712
2012-03-19 11:24:42.440133097 -04:00

This should be possible to do using padding/Insets.
