The operating system allows several valid time separators.
The time separator for presentation should always be stored externally as part of the textual data.
When you use decimal-data fields for time fields, your application needs to specify the format and time separators on the input and presentation operations.
When you use time-type fields, the time separators are always included in the time field. To change the time separators, write a CL program or high-level language routine to do the conversion.
