Public bug reported:

If the system time of server running Horizon is changed, the uptime of
instances in overview and instances tab change accordingly.

Steps to Reproduce

1) Launch an instance and leave it for few minutes.
2) Check if uptime is changed.
3) Log in to the server where horizon is started and change the time.
4) Scenario 1: Change it backward by few minutes but not less than the total uptime at the moment.
     Eg: If current uptime is 1 hour, decrease the time by 30 minutes only.
     The uptime is shows 30 minutes after refreshing the page.
5) Scenario 2: Change it backward by few minutes greater than the total uptime at the moment.
     Eg: If current uptime is 1 hour, decrease the time by 2 hour 30 minutes.
     The uptime shows 0 minutes in instances page and sometimes instance disappears from overview page.
6) Scenario 3: Change it forward by few minutes.
     Eg: If current uptime is 1 hour, increase the time by 30 minutes only.
     uptime is modified to 1 hour 30 minutes.

The above mentioned bug may affect the metering and billing if uptime is considered for calculation
Scenario 3 (By some mistake if system time is modified to future) can infact affect the end users by overcharging them, which would break the SLA.
