Time strings
A string representation of a time is a string that starts with a digit and has a length of at least 4 characters. Trailing blanks may be included; a leading zero may be omitted from the hour part of the time, and seconds may be omitted entirely. If seconds are omitted, an implicit specification of 0 seconds is assumed. Thus, 13:30 is equivalent to 13:30:00.
Valid string formats for times are listed in the following table. Each format is identified by name and associated abbreviation.
