date operators functionality: need for clarification - or, is there a BUG? #653

Open mhungria opened 6 months ago

Is the complete ISO-8601 string pattern for datetime and time values taken into account when comparing dates? If so, may be a BUG as I'm not getting a few cases reported.

string pattern for datetime: YYYY-MM-DDThh:mm:ss(.n+)?(((+|-)hh:mm)|Z)?

Needed for draft SD1205 rule (FDA Business Rule FDAB008) plus many other date comparison rules.
