After meaning to get around to it for a year or so, I’ve finally got my Qube 2 providing time public services to the NTP UK Pool. Check the current status:
pool.ntp.org: minimal’s pool servers: http://www.pool.ntp.org/user/minimal
So if you use
uk.pool.ntp.org then there a 1 in 738 chance (currently) that you’ll get data from it, or just use
ntp.minimal.org.uk for a direct feed.
