Resetting GSource timeout.

["Akshay Sumant" <sumantakshay gmail com>]

I am using GSource for registering a callback after 'x' seconds. I want to change this 'x' value before a callback gets called.
Is there any way to do this without destroying a GSource? (g_source_destroy(GSource *)). I don't want to g_free my source
hence need some method to reset a timer.
