> 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 :
> {noformat}
> ^-- 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]
> ...
> {noformat}
> 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
> {noformat}
> ^-- Node [id=684d2761, name=null, uptime=0:00:01:00:009]

> ^-- Node [id=684d2761, name=null, uptime=1:00:00:00:009]
> ...
> {noformat}
