Devon's latest suggestion is very clean and
attractive. I'll not let that discourage me from
posting what I came up with in the meantime, but I
suspect I'd prefer Devon's in practice.

As an extension to the approach of relying on
positional constants, I concocted the following:
ISOdateAsText =: '2007-08-09T10:11:12Z-13:00'
HMStext ISOdateAsText
101112
HMSnum ISOdateAsText
10 11 12
NB. Positional constants include:
ISOpYear; ISOpMonth; ISOpDay; ISOpHour; ISOpMinute;
ISOpSecond
+-------+---+---+-----+-----+-----+
|0 1 2 3|5 6|8 9|11 12|14 15|17 18|
+-------+---+---+-----+-----+-----+
NB. One method of defining these values is:
(": ,(6 4 $
'ISOp'),.'Year','Month','Day','Hour','Minute
',:'Second') =: (i.4);(10$0 1) <;.2 (15 $ 1 1
0)#5+i.15
NB. Main definitions:
HMStext =: (ISOpHour,ISOpMinute,:ISOpSecond)&(,
@:{)
HMSnum =:
(ISOpHour,ISOpMinute,:ISOpSecond)&(".@:{)
NB. The components may be used in any order, of
course.
MDYtext =: (ISOpMonth; ISOpDay; ISOpYear)&(,@:{)
I'm not thinking that my technique for setting the six
positional constants counts as good style. It just
happened to fit my fancy this evening.
