Summary

0002099: resin-admin (php) might show negative uptime for one server in the cluster

Description

Resin-Professional 3.1.3 in a Load-Balancing configuration

web-a Windows XP, Java 6, 192.168.1.100
app-a Windows XP, Java 6, 192.168.1.100
app-b Linux, Java 6, 192.168.1.141

see also attached resin.conf of all three involved resin instances.

web-a and app-b are both started and I'm logged into the php resin-administration. The page cluster.php is opened and shows that app-a is not available.
I've started app-a, waited until the console displayed "Resin started in 1657ms", and pressed "refreshed".

The Uptime column of app-a showed a negative uptime as you can see from the attached screenshot and the HTML of the cluster.php page at that time.

The clock of 192.168.1.141 (app-b) and 192.168.1.100 (app-a) differ by 86 seconds.
--> This should explain the negative uptime.

BUT, it might be worth about thinking that uptime formatting in cluster.php calculate the uptime of a server using the server's startup-time *and that server's current time* rather than the time of the server of the admin page.

Steps To Reproduce

Additional Information

Attached ZIP contains:
- php-admin_cluster__negative_uptime_format.jpg (Screenshot with negative uptime)
