>Description:
ISO-8601 (International Standard Date and Time Notation) lists three
possibilities for timezone indicators:  1) If no indicator is present,
an unspecified offset from UTC is assumed.  2) The letter 'Z' indicates
UTC.  3) A signed offset in hours and minutes from UTC (e.g., -08:00
for PST)

Strftime can generate the rest of the date and time in an acceptable
form; but has no format item which will emit the signed offset notation.
(Timezone name abbreviations are not acceptable under ISO-8601 due to
the high probability of confusion.)

For more info in ISO-8601, see:

>How-To-Repeat:

>Fix:
Add a new format specifier to emit the signed offset from UTC.  Since
'%Z' is used to get the timezone name, '%z' is a logical choice for
the offset.
