Device shows system uptime of 1 hour however the interfaces  (interfaces including ae, et, xe) shows uptime of 4 hours.

1. After the reboot, System uptime is 1 hour.
2. FPC uptime is 1 hour.
3. But some of the interfaces shows uptime as 4 hours (interfaces including ae, et, xe).

• Some of the interfaces shows incorrect uptime due to NTP Server being not in sync during the time of reboot.
