The CPMC displays times in different contexts:
You can choose which time zone the CPMC uses to display all times. You have the choice between GMT and local time to be used for the display of date and time data. The local time zone is determined by your browser settings. This setting does not have an influence on how times within time conditions of policies are stored in the z/OSMF repository or the file system; they are always stored in GMT. When you switch the CPMC to a different time zone, all dates and times are adjusted.
Policies contain time conditions that define time periods during which additional capacity can be provisioned. Recurring time conditions define weekly repeating periods. They describe the time of the day when provisioning of additional capacity is allowed and the days of the week to which these times apply.
The CPMC time zone is used to display the dates and times contained in the time conditions. If a time zone with daylight saving time is specified, the actual date and time values used might be one hour later or earlier than the values displayed.
If due to a time zone switch the start time of a recurring time condition moves to a different day, the checks for the selected days of the week are moved accordingly.
