timer1 in 16f877a

I am currently working on a project which requires me to time something in milliseconds. I manage to get the Timer1 in 16F877A to run in the fastest of 10 millisecond interval.

Can any experts guide me to achieve in 1 millisecond interval? I am coding using PicBasic Pro.

Hope can help me, urgent. Very much thanks!

With a 20MHz clock and without prescaler (1:1), Timer 1 has 200nS resolution. It will have counted to 5000 when a millisecond expires!
