Separate field to specify time zone
It would be awesome to have a tconvert tab. Selectable time zones for each IFO in the world, plus UTC and gps. For the time zones, I want to be able to select e.g. "Pacific", and it will figure out if it's PDT or PST, because I can never remember.
Another possible awesomeness would be for the crosshairs cursor to have tick boxes for what time unit you want displayed. So if I check crosshairs cursor and Pacific and UTC, it will give me the time in both my time zone, and UTC.
