Container free time, demurrage, billing deadlines, bill of lading dates and EDI timestamps.

Signature

isValidX12DateAndTime(date: string, time: string): boolean

Return true when the date and the time of an X12 segment, sent as two elements, together state a real local date and time.

Element	Name	The dictionary’s definition
373	Date	“Date expressed as CCYYMMDD where CC represents the first two digits of the calendar year”
337	Time	“Time expressed in 24-hour clock time as follows: HHMM, or HHMMSS, or HHMMSSD, or HHMMSSDD”

True exactly when parseX12DateAndTime returns a date-time for the same arguments: the validator calls the parser, so the two cannot disagree.
Both elements are required. A missing or empty date or time is false: check a date alone with isValidX12Date(value, "D8") and a time alone with isValidX12Time.
Checks the calendar as well as the shape: 29 February 2023, 31 June, hour 24 and minute or second 60 are false.
The date has a four-digit year and the time is 4, 6, 7 or 8 digits: a date of six digits and a time of 5 or 9 digits are false.
False for a non-string argument.

Parameter	Type	Description
`date`	`string`	The data element 373 date as transmitted, `CCYYMMDD` (e.g. “20240615”)
`time`	`string`	The data element 337 time as transmitted (e.g. “1430”)
