Where did you get this idea from? Not only is shipping not free, but the
official carrier (China Post) is quite expensive - to the point where
many people will either use private couriers (for Chinese internal
shipments) or will courier things to HK and send them via HK post (for

There is already a time scale that is extensively used that has no leap

Hi,
This is the log from my gpstm.

I'm not a huge fan of leap seconds for enterprise computing enviornments unless
there is a regulatory or other legal requirement for the system time to exactly
match legal time.
I'm quite happy that my own personal time server didn't support the leap second

Hi,
From: Poul-Henning Kamp p...@phk.freebsd.dk
Testing software for correct handling of leap-seconds is a major undertaking
which very few people have the kit and skill to do.
A software that crashes/behaves badly when the time is updated is a bad
software.

Yes, platitudes like that make for good sound-bites, but it doesn't
bring us any closer to a solution.
I am not considering timescale.
What happens to your system if you set the clock in the past by hand?
Mine continues working has it should be.

This just moves the problem. The software still has to use UTC when
talking to the rest of the world.

Time and the sun are certainly a _natural_ connection, not an artificial
