Q:

Does it sync the clock with an NTP time source ? PC/mobile clocks often are only roughly aligned and can have errors of several seconds.

Did you know about the Telstra time service - "George The Speaking Clock" - which can be called on 1194 ? The point is that this is synced to the national atomic time standard provided by CSIRO and is accurate to fractions of a millisecond.

Comments:

1. There's no point showing hundredths of second when human reaction times are of the order of 0.1-0.3 second, and the clock accuracy may not be much better if relying on NTP. Even 0.1 second is pointless.

2. I'd add a means to record events to a log, where an "event" is a key pressed (spacebar would do) or mouse click and it records the time of the event in UT or local time.

This could be used for example to do occultation timings (moon and planets) or Bailey Bead timings (solar eclipse).

3. If you had used XOJO you could make this

(a) a web app, for anyone with a web browser,
(b) a self-contained desktop app desktop for all-comers - Windows/Linux/OSX - without requiring MONO or compilers.
(c) iOS - iPhone/iPad app,
(d) Raspberry Pi.

And all from the same codebase.
