-187 A REFERENCE TO A CURRENT DATETIME SPECIAL REGISTER IS INVALID BECAUSE THE MVS TOD CLOCK IS BAD OR THE MVS PARMTZ IS OUT OF RANGE

Explanation
 DB2® has
encountered an invalid time-of-day (TOD) clock. The user referenced
one of the special registers: CURRENT DATE, CURRENT TIME, CURRENT
TIMESTAMP, or CURRENT TIMEZONE.  If the user referenced CURRENT TIMEZONE,
the MVS™ parameter PARMTZ was
out of range.

System action
 The statement cannot be processed.

Programmer response
 For CURRENT TIMEZONE, check that the MVS parameter PARMTZ is between -24
and +24 hours.  For the other CURRENT special registers, check that
the MVS TOD clock has been set
correctly.
