It sure would make life easier if we could get: X-Weave-Time: ms X-Weave-Timestamp: 1323393518040 rather than decimal seconds. Milliseconds since epoch. Parsing and validation is a bitch. Default to the old format, of course. Add to docs. Request header for time format. Yadda yadda. (Same goes for info/collections, actually.)
It'll be centiseconds (hundredths), and it'll be the format in 2.0. Not sure we need X-Weave-Time as well.
Correction. It will be in integer milliseconds for everything
This has now been committed for sync2.0, timestamps are integer milliseconds throughout
Already done and in code.
