The PCM (powertrain control module) uses the EOT (engine oil temp) sensor and the BARO (barometric pressure) sensor to determine how long the glow plugs will be on. The PCM energizes the glow plugs longer if the engine is very cold or if the barometric pressure is low. There is no timer involved as in the pre OBDII powerstroke.

Outside tempature and time coolant temp too. Diesel sure has come a long way the new F-350 with two turbos really is nice. Even more powerfull than 1996

It is temp controlled, when the glow plugs reach the optium temp the light goes out.

It tells you not to start cranking the engine until the glow plugs have done their job heating up the air in the cylinders so it will start.

There might be a problem with the glow plug, or a fuse. Your best bet is to take it in to get it checked.
