Time change–fall back–this weekend!

Fall Back

This weekend, the time changes for many areas of the country–“fall back”. As you walk around your residence changing the time on watches, clocks, microwave ovens, and personal electronic devices, don’t forget your “diabetes-related” devices; they may not change time automatically. The data memory in your blood glucose meter is saved according to the time of the test; it needs to be correct. The time set in your insulin pump &/or continuous glucose monitor (CGM) determines your personal settings, including basal and bolus rates. Additionally, the “insulin on board” feature and time of your boluses is directly tied in to the time set in a pump. So the time setting is very important and needs to be accurate. You may also need to synchronize the clocks on your computer software diabetes data management systems to maintain the accuracy of time for data saved and downloading purposes.

After you have programmed the new time, always double check your settings, especially that the AM/PM setting is correct. The Users Guide of your products can direct you on the procedure to follow, or contact the Customer Support departments of your various devices via their website or by calling the toll-free phone numbers usually found on the back of the device; they may request the serial number of your equipment. This same information is also important if you are traveling to different time zones, any time of year.
