I started the box and for a minute didn't see the negative up time but one minute later I again saw that Squid cachemgr is again reporting the negative uptime. Can you suggest what is going wrong?

Regards,
Saurabh

I am checking if someone tried changing the system time. Thank You Keith.

Another possibility is that when your system booted, it started with
a initial system boot time "in the future", and the boot time was later
"corrected" in the system startup by ntp synchronization.
