I am looking to stay on true time, the real issue here in those 
installation is not realy having the perfect time but that all the 
device in the field have the same time. There are new ways to acheive 
this  such as IEEE 1588 but since no one is ready for this using GPS 
device is our closest friend. But it's funny you asked, soon we will 
tackel simple synchronous switching of breaker and then we'll have to 
keep up with the AC cycles
