HP Support document

Businesses and individuals whose environments are sensitive to date and time transactions and utilize a local time zone may be impacted by changes in the Daylight Saving Time rules. In addition, some applications perform date and time manipulation and may make automatic decisions based on Daylight Saving Time rules. Although this situation should be rare and HP has not identified any particular applications run on x86 servers that make decisions based on Daylight Saving Time, ProLiant customers should be aware of this possibility and take corrective action if they believe they may be affected.

HP recommends customers perform a system assessment to understand what updates may still need to be installed by March 11 to allow for the automated adjustments for the Daylight Saving Time changes to occur.
