[main] Try to avoid false clock drift warnings
If the browser tries to recover the state of a page after a restart, it
will re-check for clock drift using stale data. Let's hope the browser
will also restore sessionStorage in this case; we store the time of
check in there, to prevent another check after the page is restored from
cache.
