APAR Error Description / Circumvention

-------------------------------------------------
Results from the combination of PASE runtime functions
read_wall_time() and time_base_to_time() may be incorrect,
including cases that make it appear time moved backwards.  This
issue is more likely when the system clock is adjusted by the
IBM i adjtime() function.  The Network Time Prococol (NTP)
TCP/IP server uses adjtime().

CORRECTION FOR APAR 'MA44283' :
-------------------------------
Results from the combination of read_wall_time() and
time_base_to_time() will never make it appear that time moved
backwards.

The system no longer updates fields Xint and Xfrac in the PASE
_system_configuration data structure for system clock adjustment
(matching AIX).

CIRCUMVENTION FOR APAR 'MA44283' :
----------------------------------
None.
