lower monotonic uptime resolution from MILLISECONDS to SECONDS
The monotonic uptime was used exclusively with caches and having
a resolution of SECONDS allows it to be stored as an int without
risk of wrapping (~68 years). Using MILLISECONDS meant that it
would wrap after ~25 days which is totally possible and EXPECTED.
Just as an example, the small test server I ran for about 1 month
had ZERO downtime on the QueryManager except for when I manually
restarted it. It was probably very close to wrapping when I took
it down.
