7.3.2.7 Global and System Level GMT Time Offsets


The raw data time and datetime fields in the SMF type 120
records are recorded in GMT time.  The raw data time and
datetime fields in the SMF type 103 and the USS generated WEB
log files are recorded in local time.

In order to allow you to store all WEB related data in local
time, regardless of the data source, two optional statements
are provided:

o  GLOBAL GMTOFF +/-nn.nn
o  GMTOFF orgsysid +/-nn.nn

These statements, if coded, only affect the date and time
related data elements in the files created from the SMF type
120 records.  The SMF type 120 record subtypes processed by
this analyzer are described in section 6.2.1.2.

The following Web Analyzer files are created from the SMF
type 120 records and will be affected by use of the GMT time
offset statements:

o  WEBHPI   JVM Heap Interval File
o  WEBSAF   WAS Server Activity File
o  WEBSIF   WAS Server Interval File
o  WEBMIJ   J2EE Method Interval File
o  WEBHTP   HTTP Session Manager Interval File
o  WEBSRV   WebContainer Servlet Interval File

Refer to section 5.2 for more information about these files.

Note that the time offset only affects the date and time
fields in the CA MICS database records, but does not affect
the datetime stamp in the prefix.MICS.CHECKPT.DATA data set.
That time stamp represents the time and date that SMF data
was written to the SMF buffer and is already in local time.

The GMT time offset statements are described in the following
sections:

1  GLOBAL GMTOFF +/-nn.nn Statement
2  GMTOFF orgsysid +/-nn.nn Statement
