I tend to say ENOTABUG, as they are cases of “be liberal in what you accept”
and they match the regular expression. If they wouldn’t match that, *then* an
exception would be thrown.
$ 6 'DateTime.new("2000-01-01T00:00:00+0000").say'
2000-01-01T00:00:00Z
$ 6 'DateTime.new(“2000-01-01T00:00:00-00").say'
2000-01-01T00:00:00Z
$ 6 'DateTime.new("2000-01-0\x[666]T00:00:00").say'
2000-01-06T00:00:00Z
They all seem to generate the correct DateTime object. Note that if there is
an error:
$ 6 'DateTime.new("2000-01-0\x[666]T00:00:90").say'
Second out of range. Is: 90, should be in ^61
$ 6 'DateTime.new("2000-01-0\x[666]TOOMUCH").say'
Invalid DateTime string '2000-01-0٦TOOMUCH'; use an ISO 8601 timestamp
(yyyy-mm-ddThh:mm:ssZ or yyyy-mm-ddThh:mm:ss+01:00) instead
