I do.
I am a bit particular about accurately knowing the current time so I have set up two Stratum 2 NTP time servers at home. One syncs from the atomic clocks run by the National Measurement Institute in Australia (they are the folks that define the official time in Australia) and the other connects to GPS clocks run by various Australian universities.
As a result, all computers in my home are accurate to within one thousandth of a second of the official time.
Having a pair of Stratum 2 servers and not sharing them seems a bit selfish, so I have recently registered as a member of the NTP Pool which provides public access to accurate NTP servers. If you sync from *.au.pool.ntp.org then there is a chance that you are getting time from my servers. You can also add ntp.paulmccormack.com as a server if you want.
Performance information on my server can be found here.
There is no excuse to be late any more!
