Quick time delay check - 7:52:00 . . . NOW!

OK, it's currently 16 seconds off.

Maybe a black hole is skirting past the solar system and it's bending spacetime just a little bit. Have any astronomers actually checked for this? This is the last thing we need!

If Hard Sun is to be believed, a black hole could be hoovering up the sun right now but nobody in the half of the world currently in daylight will have noticed and it'll only be when the sun rises over London that the penny will drop.

Sounds like you've got too much time on your hands.

You are James Bond about to dispatch the film's main villain by impaling him with a grandfather clock and I claim my £5.

Time delay check - 1:32:00 . . . NOW!

. . . now 25 seconds off reality.

Ambient Sheep

Test at 10:39:30.

EDIT: Yeah, server time is 34 seconds behind my Rugby clock.

Mind you, just checked the clock against https://time.is and it's six seconds fast (it's never been the same since they moved the transmitter, the bastards), so server only 28 seconds behind.

Ambient Sheep

Test 2 at 10:43:20 on time.is.

EDIT: yes, confirmed, 28 seconds.

Boh! That didn't work - lets have another go :

This website is running slow - no idea why, maybe something to do with that bit of code Blumf posted?

Anyway, in order for my posts to show up on this site at a specific time, such as 2:00:00pm [for crackpot OCD 'control' reasons], I have to post in here to work out the time delay, and then factor that time delay in for the rest of the posts for that day (or hour!)

e.g. - to get the timestamp on CaB showing up at a sharp 11:20:00pm, I'd (currently) have to wait till ragged old 11:21:17pm, and post it then - like I did with this one.

That's just showing my system's time sources and accuracy (within 60ms at that point, seen better)

On Linux systems you can run special software that tracks and maintains the clock (as opposed to the occasional check and set that Windows does (last time I er.. checked))

Some examples:
NTPd, the default reference implementation
chrony, a more featureful implementation (which I'm using)
and timesyncd, systemd, yuck. But common.

Might be an idea to get one of these running on the server, if it's clock is drifting as fast as it seems to. Over a minute in about a month is terrible.

It's losing more than a second a day.  My pc clock drifts a little, but it's set to synchronise to a timeserver once a week, surely the server the forum is hosted on should do something similar?

WAHEY - it's fixed!
