I'll try to make such a script, it can be done with so called RegExp's
But the only limitation is that the script is not psychic, it can't see if you meant a number or a time. So you need to write the time like "9pm" or "9:00", "see you at 9" won't work

Btw, can someone tell me the most common ways to write time?
9pm, 9:00, etc
