It's correct within wristwatch-and-eyeball accuracy for me right now.

*.pool.ntp.org entries are *pools* of NTP servers run by whoever owns a
particular one, so technically, the pool doesn't *have* a single
inherent time (available from all members equally) that the website
could display. Identify the (single ... ?) *IP* your servers currently
poll so that *that one* public server can be scrutinized.

And prepare to use *several* pool servers instead of one, recommended
precisely to avoid such a scenario.
