OT : Trader's clock?

[Abhijit Dey <omegalist@xxxxxxxxxx>]

I have seen many of them, but just can't find what I need. I am not 
really looking just for a "bar completion" alert type of clock. I need 
programmable onetime / multiple alert. Something like:

a) Beep me at 12:27 and tell me what to look for
b) Beep me at 15:02 and tell me what to look for
c) Beep me every 30 min, starting at 08:28 and tell me what to look for

Any software utility that I can use?

Thanks,

Abhijit
