Description

Ignite prints a metrics to the log with uptime, formatted as 'XX:YY:ZZ:TTT'.
It looks, like XX corresponds to hours, YY to minutes, ZZ to seconds, however if we filter uptime metric from a long running server (few days), we would see that :

 ^-- Node [id=684d2761, name=null, uptime=00:01:00:009]
 ^-- Node [id=684d2761, name=null, uptime=00:02:00:009]
 ^-- Node [id=684d2761, name=null, uptime=00:03:00:009]
 ^-- Node [id=684d2761, name=null, uptime=00:04:00:021]
...
 ^-- Node [id=684d2761, name=null, uptime=23:58:08:391]
 ^-- Node [id=684d2761, name=null, uptime=23:59:08:393]
 ^-- Node [id=684d2761, name=null, uptime=24:00:08:395]
 ^-- Node [id=684d2761, name=null, uptime=24:01:08:406]
...
 ^-- Node [id=684d2761, name=null, uptime=59:59:23:542]
 ^-- Node [id=684d2761, name=null, uptime=00:00:23:554]
...

BUG:
1. hours do not rollover at 23:59:59
2. there's no simple means for user to get uptime days, because hours do actually rollover after 59:59:59

what is expected:
1. add a day counter, init with 0
2. make hours correctly rollover after full day (24hrs) run

 ^-- Node [id=684d2761, name=null, uptime=0:00:01:00:009]
...
 ^-- Node [id=684d2761, name=null, uptime=0:23:59:00:009]
 ^-- Node [id=684d2761, name=null, uptime=1:00:00:00:009]
...
