microsecond counter

[jackolim]

Hi, I currently doing a simple TCP assignment using Labview 7.0. As a
client, i sent a message to server which will reply(echo back) the
message. The problem i face is i could only measure the delay (round
trip time) in ms(using the ms counter inside labview). Is there any
way to measure the delay in terms of microseconds? Or can access the
CPU clock to measure? Thanks..
