best way to create a timer

[Alexnb]

I am wondering what is the best way to create a timer, like an alarm, once it
reaches a time, it triggers an event. I have a way of doing this but it
seems like it isn't good at all. If it helps at all I am using a Tkinter,
but that probably doesn't mean much. The way I was doing it was using a
while loop, and just saying while current time is not = to trigger time, do
nothing, and when it is, do event.

You can think of doing with import time module and time.sleep(n) but
you have to calculate n in seconds.

I think that threading.Timer could be what you're searching for.

Tkinter makes a big difference here. Like most (all?) event loops, it
provides a way to call a function after a specified amount of time.

Here's two pages I found:

http://www.astro.washington.edu/owen...ary.html#After

Note that it only fires once. If you want it to fire again you're
callback will have to setup another timer.
