i think linux provides even micro sec resolution timer. is the timer is going to run in application or kernel area.( eg by using settimer can use micro sec timer)

hi arul thanx for reply,
my problem is that i have to implement the synchronized channel switching mechanism . i am using gps time with an input of 1pulse per second,as an refrence point for starting the synchronization timer. one synchronization interval is about 100ms,such that after every 50 ms their is a channel switch. now the problem is how to get timer resolution in milliseconds if i have to use the timer in kernel ?
