INNOVATION DATA PROCESSING ANNOUNCEMENTS

DST - Daylight Savings Time

For all of Innovation’s mainframe products, including:

• FDR, FDREPORT and FDRABR
• FDRPAS and FDRERASE
• FATS, FATAR and FATSCOPY
• IAM

there is no impact from the USA Daylight Saving change in 2007 (DST2007). Many of these products may use the time and date to record timestamps or set dates in dataset labels, but they always pick up the current time and date, however it is set. It is the responsibility of the installation to change the time and date appropriately, either manually (console SET command) or with some sort of automation.

There is one consideration for FDRABR. This has nothing to do with the DST2007 change, it has always existed:

• FDRABR gets the date at the start of execution and uses it for various purposes, such as checking for ADAYS= (days since last use) and CRDAYS= (days since creation) in ABR Archive.
• If an ABR Archive job is started after midnight, but before 1 AM the time is set back an hour, making it the previous day, then ABR may inappropriately select data sets based on the original date.
• So, Innovation recommends that an installation using ABR Archive be sure not to change the time during the hour immediately after midnight. Many installations use 2 AM as the time to change the clock.
