indicator, do we? Even though this is supported by ISO 8601, as well as W3C
schema, can we profile this out of our spec?
I tend to feel that we should not profile things out.. only discourage their
To time zone.. it can be viewed as something relevant to hour.. and thus
illogical as applied to objects of coarser readability.. but it can also be
viewed as a specification of geographical locale of the speaker.. and as
such not without meaningful use..

fraction of a second?
8601 uses hh:mm:ss.fff where fff are milliseconds..
where ss are rational seconds. e.g. ss including decimal fractions without
restriction, e.g. allowing for times such as 12:21:44.5 and 12:59:59.1001
Do we use "." or "," or both for decimals, e.g. 12:24:23,2 or 12:24:23.2 ?
I would suggest both.

Of course we do! Currently 7 countries have time zones that are not aligned
with hours.. these include Canada, Australia... Nepal is UTC + 5:45 so not
even 1/2 hour ...
