5.74 SYSEPOCH (Base date for TOD clock)
5.74.1 Function
SYSEPOCH specifies the base date for the TOD clock. Use the default value (1900) for all systems
except OS/360. Use 1960 for OS/360. Values other than these were formerly used to offset the TOD
clock by a number of years to move the date before the year 2000 for non-Y2K-compliant operating
systems. This use is deprecated and support will be removed in a future Hercules release after which
only values of 1900 or 1960 will be accepted.
