Try patching src/vppinfra/time.[ch] from master/latest. The algorithms involved
have been changed quite a bit since 18.01...

Subject: [vpp-dev] VPP main threads gets stuck when system time is changed
Hi,
We have VPP 1801 in one of our systems. I understand the support for VPP 1801
is not there anymore , but requesting for any advice nevertheless.
System time is changed by a few seconds using 'date -s'. Then the VPP main
thread goes to 100% CPU utilization.
The issue is only reproduced when the traffic is running.
I attached gdb to VPP and saw that while the worker thread is working normally,
the main thread seems to be stuck at clib_cpu_time_now.

Also, here is the bt of main :

Please help. Any pointers will be much appreciated
Regards,
Siddarth
