Time.utc uses timegmw() and it uses leap second information.
If the given time is larger than known_leap_seconds_limit, it calls
find_time_t, which uses localtime(3) and calls stat(2) in it.
This patch avoid it by setting known_leap_seconds_limit to 0 if the timezone doesn't have leapsecond information (if no leap second is found "now", I assume the timezone doesn't have leapsecond information).
