ISO4T
All ISO4 input formats.
If the prefix "T" is used then the absolute time component can use the input format hhmmss as well as the standard hh:mm:ss. For example:
Acceptable: yyyymmddThhmmss, yyyymmddThh:mm:ss, and yyyymmdd hh:mm:ss
Not acceptable:
yyyymmdd hhmmss
Acceptable:
'Thhmmss', 'Thh:mm:ss' and 'hh:mm:ss'
Not acceptable:
'hhmmss'
This is the only case where an absolute time can be entered in format hhmmss instead of hh:mm:ss. To avoid ambiguity, a time field entered in hhmmss format must be 6 characters long.
yyyymmdd
ISO4 output format, unless the date includes a time, in which case the format is: yyyymmddThhmmss
ISO4TC
See description under ISO4T.
ISO4 output format, unless the date includes a time, in which case the format is:

For a date that is missing the century on input, year is determined by the setting on the II_DATE_CENTURY_BOUNDARY environment variable.
In three-character month formats, for example, dd-mmm-yy, specify three-letter abbreviations for the month (for example, mar, apr, may).
To specify the current system date and time, use the constant, NOW.
