..., and seconds:
YYYY-MM-DD-HH.MM.SS
Each segment can range from all zeros to all nines. For example a Duration of 0001-00-01-00.10.00 is a year, a day, and ten minutes. The only limitation is that the result date (RTNVAL) must fall between January 1, 0001 and January 1, 10000.
The base timestamp (DTETME) can be any valid timestamp value in YYYY-MM-DD-HH.MM.SS format.
DTETME, DURATION, and RTNVAL are CHAR(19) CL variables.
The calculations are performed by built-in functions.
