-------------------------------------
Summary: Incorrect uptime in GG metrics for long running server
node (1+ days)
Key: IGNITE-8138
URL: https://issues.apache.org/jira/browse/IGNITE-8138
Project: Ignite
Issue Type: Bug
Components: general
Affects Versions: 2.4, 2.1
Reporter: Max Shonichev
Fix For: 2.5
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 :

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
