HHMM, HHMMSS, HHMMSSD, or HHMMSSDD.
Choose from the list to specify seconds and degrees of accuracy, for example:
2359 = 11:59PM
235959 = 11:59:59PM
23595999 = 11:59:59.99PM
The time is expressed in 24-hour (military) clock time as follows: HHMM, or HHMMSS, or HHMMSSD, or HHMMSSDD, where H = hours (00-23), M = minutes (00-59), S = integer seconds (00-59); and DD = decimal seconds; decimal seconds are expressed as follows: D = tenths (0-9) and DD = hundredths (00-99).
