Almost all were easy to replace, except ones exposed via JSON which
have been left as-is.
The linter has a cool behavior where it flags attempts to pass
`atomic.Int32` for example by value , which is always a mistake,
say as an argument to `fmt.Sprintf()`
The dual time measurement is described in
https://go.googlesource.com/proposal/+/master/design/12914-monotonic.md
The fix is to discard hidden monotonic time component of time.Time
by converting to unix time and back.
Reviewed usage of clock.Now() and replaced with timetrack.StartTimer()
when measuring time.
The problem in #1402 was that passage of time was measured using
the monotonic time and not wall clock time. When the computer goes
to sleep, monotonic time is still monotonic while wall clock time makes
a leap when the computer wakes up. This is the behavior that
epoch manager (and most other compontents in Kopia) rely upon.
Fixes#1402
