J ef1b125c3e zuse: fix time fix regression
Fixes #4598.

#4474 made the JSON time conversion no longer invertible, which caused
problems for chat, which uses message timestamp in milliseconds as a key
-- so chat would send a message with ms timestamp x, it would get
encoded as @da x, but then when it went back through the conversion to
milliseconds, it would often (not always) get encoded as x-1.

I still do not fully understand why this is -- and why it doesn't seem
to be a problem with seconds based on cursory testing -- but integer
multiplication and division generally do not invert. And adding a half a
millisecond to the input date before converting it resolves the issue
and makes the functions invertible.

I added a regression test, so hopefully the next courageous adventurer
who winds up here after wondering why +unm looks funny will have a
safeguard against some of the mistakes I made.
