This should be proper way to adjust time incrementally without causing jumps one in +/- direction. Time-sensitive services might be confused by huge jumps. This also implements timed healh check based on first successful time sync. Fixed some random health check related issues in other services. Signed-off-by: Andrey Smirnov <smirnov.andrey@gmail.com>
