IDEA: Time Sync Differences?

[ag0044]

This is pure curiosity on my behalf.

By way of background, I use Dimension4 to synch the time on my PC with my ISP's time-server and that seems to work fine for me and my PC. D4 offers a range of different time-servers, but you can only nominate one as your time-server.

I wondered, what if my chosen time-server is just a wee bit inaccurate? (Note1: if it is, the difference is probably of no consequence to me in my everyday usage. Note2: given Note1, what do I care? Note3: "wee bit inaccurate" is deliberately vague.)

Is there an app which will check a number of differing time-servers at the same instant and report back to the user what results it gets from each time-server? (If I was using this app, I would run it manually, probably no more frequently than once a month, at most.)

Thanks

If you are willing to run it manually and infrequently, it may be just easier to google terms - united states atomic time

you'll get a few time servers such as nist

usually it has a map of the US and you click your area to compensate for time zone daylight time etc..
