Hi Bert, I was saying ISO8601 do support this - it is openEHR that constrains to milliseconds.

In my case it is action potential measurement from myocytes

Cheers,

Just for the record, which medical requirement makes measuring micro-seconds necessary?

By the way, ISO allows one or more digits to represent a decimal fraction of a second.

I don't have the original standard at hand, but Wikipedia says:
https://en.wikipedia.org/wiki/ISO_8601
There is no limit on the number of decimal places for the decimal fraction.

Hi,

I have a requirement to capture timeseries data which happens at 250 microseconds - that is 0.000250 seconds.
While many programming languages, and the ISO8601 spec, supports this  openEHR RM<http://www.openehr.org/releases/RM/latest/docs/support/support.html#_iso8601_time_class> seems to be constrained to milliseconds:
hh:mm:ss[,sss][Z | ±hh[mm]]

Any particular reason we dump microseconds? If not can we add this capability - I think it won't break any existing code (I hope!)
