All IRT and Debit/Credit Card Offices: Setting Clocks for Daylight Saving Time

Managers must ensure that before opening for business on Monday, March 9, 2009, the clocks in all integrated retail terminals (IRTs) and debit/credit card terminals under their control are set forward (in most locations) 1 hour to reflect the change to Daylight Saving Time. Facilities with Satur­day night operations should reset the time as soon as possible after the 2 a.m. start time, Sunday, March 8, 2009.

The correct system time in IRTs is critical since their internal clocks are used to verify Express Mail® and Global Express Guaranteed® acceptance times and service com­mitments. The IRT system time is also printed on customer receipts and employee reports. It is very important that the debit/credit card terminal clocks be set to the correct day, date, and time, as this will help reduce the possibility of accepting an expired debit/credit card.
