Goal

This document will clarify the support policy for Daylight Savings Time (DST) for the Midrange platforms listed in this article.

Solution

These Platforms are in End of Life (EOL) status. In this status, only software defects are being remedied within System Controller Application (ScApp). DST changes are not software defects and there is also a reasonable workaround to adjust for these time changes.

The Midrange Server system controller was last updated for DST rule changes in System Controller Application (ScApp) 5.20.12. The System controller firmware is currently updated with DST rules up to Olsen tzdata2008i.

Workaround:

The use of GMT offsets is suggested for regions that have changed since Olsen tzdata2008i to maintain proper time on the System controller. Use the command, 'setdate [-v] -t GMT <+|-> offset-from-GMT', which is documented in the Command Reference Manual to adjust to GMT on the SC as needed. It is also strongly suggested that Solaris DST patches be applied on the platform domain(s) to keep it's time in sync with any changes to DST throughout the world (Solaris DST updates continue to be made in most versions).

For a more complete discussion of how the System Controller and Solaris clocks are related see 1004720.1.

There is currently a Change Request (CR) open to track customer who wish to
have this product updated regularly for DST changes. That CR is CR 6986452.
Any customer wishing to get ScApp upgraded with future DST rules should
be added to that CR.
