Hi Andy

Your internal ticket #630 gave rise to external ticket http://bugs.icu-project.org/trac/ticket/10962, which claims to have fixed the API docs to clarify the behaviour.

fractional second - truncates (like other time fields)
to the count of letters when formatting. Appends
zeros if more than 3 letters specified. Truncates at
three significant digits when parsing.

S
SS
SSS
SSSS

2
23
235
2350

I can't see anywhere that addresses your point about about abutting versus non-abutting numeric symbols though?

As far as DFDL spec is concerned, this is what we say today:

fractional second (see note 1)

Number

SSS

235

There is no 'note 1', I think the note was made into a normal paragraph, which reads:

Any number of fractional seconds "S" may by specified in the pattern and accepted by implementations, but an implementation is free to represent a limited number of fractional seconds internally. Excess fractional seconds are truncated, not rounded up. At least millisecond accuracy must be implemented. Unlike other fields, fractional seconds are padded on the right with zero.

Hi Steve

Re agenda item 2 and calendar patterns with 'S', this ICU ticket from last year might be relevant - https://icu.sanjose.ibm.com/gcoctrac/ticket/630. It seems that the error reporting may also depend on whether the pattern has 'S' on it's own or next to other numeric pattern entities. i.e. 'HHmmssS' is subject to length checking, but 'HHmmss S' is not, due to the space before the 'S'.

HTH,
Andy
