I am making a missed call phone verification system in which a user has to do a missed from his phone within 2 minutes of registration to verify his registration. Upon successful registration, the registration time is saved in database in format like 07:55:43 (hr:min:sec).
What I want to do is that user has to do missed call within 2 minutes of registration only (I can also get the time of when he called in hr:min:sec format) & if he doesn't do call in 2 minutes then die() should execute..
How can I do that?
