I am looking ways to pick a random number in milli seconds from a range of 2 minutes and allow the SAS process to sleep for that period:
I am currently using call sleep function, for SAS to sleep for a fixed amount of time.
Can any one please help!

You must choose a minimum and maximum value for the sleep range. You said "a range of 2 minutes," so I am going to assume that you mean that you want the sleep interval to be between 0 milliseconds and 120,000 milliseconds:
t = 120000 * rand("Uniform"); /* in range [0, 120,000] */
call sleep( t, 0.001); /* time in milliseconds */
An alternative way is to specify the sleep interval in seonds:
t1 = 120 * rand("Uniform"); /* in range [0, 120] */
call sleep( t, 1); /* time in seconds */
