After DST changes, when entering the SCMSYS, System Condition Monitor panel of SYSVIEW, the LastUpdt field is showing 1 hour ahead as if it did not pick up the time change. However, the TIME command returns the correct value.

SYSVIEW 14.2, SYSVIEW 15.0, SYSVIEW 16.0 - GSS (Common Services 14.1, Common Services 15.0)
The controlling factor in SCM is GSS. The SCM command gets it data from GSS. GSS does not continue to check the CPU time once it is initialized. It keeps its own internal running clock once it is brought up. Some IMODS utilize the GSS internal clock to wake up or perform a specific function.
GSS needs to be recycled when Day Light savings time changes occur.
