The TIMFMT keyword allows the specification of a default external time format and a default separator (which is optional) for all time fields in the program-described file. If the file on which this keyword is specified is indexed and the key field is a time, then the time format specified also provides the default external format for the key field.
For a Record-Address file this specifies the external time format of time limits keys read from the record-address file.
You can specify a different external format for individual input or output time fields in the file by specifying a time format/separator for the field on the corresponding input specification (positions 31-35) or output specification (positions 53-57).
See Table 36 for valid format and separators. For more information on external formats, see Internal and External Formats.
