Timer and Time Conversion Services
$TIMCON Converts Coordinated Universal Time (UTC) to 64-bit
system format or 64-bit system format to UTC based on
the value of the convert flag.
10.4 Utility Routines
Some OpenVMS utilities can be invoked either at the DCL command level or
through a callable interface. Other utilities have only a callable interface. A
utility with a callable interface means that a program can invoke the utility,
execute utility-specific functions, and exit the utility. Table 10–4 summarizes the
utility routine groups.
For complete information on the utility routines, and a routine-by-routine listing,
refer to the OpenVMS Utility Routines Manual.
