The following time stamps are entered into a backup file created by GUARDS-SAVE and in the saved guards:
Creation date of the backup file
When it creates a backup file, GUARDS-SAVE enters the date and time of the backup together with other information in a special data record. The time is stored in UTC format (Universal Time Coordinate). This time is converted into local time, for example before a GUARDS-SAVE log is displayed.
The creation date and the last modification date of the guards
Each guard contains two time stamps which indicate the date and time of creation and the last modification. The time stamps are stored unchanged in UTC format. This time is converted into local time each time a guard is displayed. The guards restored under program control are given a new current creation and modification date. The new creation date is a result of having to set the guards up again during recovery. The modification date results from recovering the guard contents.
Times defined in access conditions (guard type STDAC)
Times defined in access conditions TIME= , always relate to the local time without considering seasonal changes (summer and normal time). These times are saved and restored unchanged by GUARDS-SAVE.
