These pumps need a special care because AAPS is using history from the pump but the records in pump don't have timezone stamp. **That means if you simple change timezone in phone, records will be read with different timezone and will be doubled.**

So the Insight user doesn't have to worry about timezone changes and time changes. There is one exception to this rule: The Insight pump has a small internal battery to power time etc. while you are changing the "real" battery. If changing battery takes to long this internal battery runs out of energy, the clock is reset and you are asked to enter time and date after inserting a new battery. In this case all entries prior to the battery change are skipped in calculation in AAPS as the correct time cannot be identified properly.

## Timezone Change for Accu-Chek Combo

63
The [new Combo driver](../CompatiblePumps/Accu-Chek-Combo-Pump-v2.md) automatically adjusts the time of the pump to the time of the phone. The Combo cannot store timezones, only local time, which is precisely what the new driver programs into the pump. In addition, it stores the timezone in the local AAPS preferences to be able to convert the pump's localtime to a full timestamp that has a timezone offset. The user does not have to do anything; if the time on the Combo deviates too much from the phone's current time, the pump's time is automatically adjusted.
58
64
59
65
Note that this takes some time, however, since it can only be done in the remote-terminal mode, which is generally slow. This is a Combo limitation that cannot be overcome.
60
66
61
67
The old, Ruffy-based driver does not adjust the time automatically. The user has to do that manually. See below for the steps necessary to do that safely in case the timezone / daylight savings is the reason for the change.

Depending on your pump and CGM setup, jumps in time can lead to problems with **AAPS** to function correctlyy.

For instance with the Combo pump, the pump history is read twice leading to duplicate entries. For some pumps it is better to make time zone adjustments while awake and not during the night.

### DST automatic adjustment for most pumps
86
+
87
+
* This adjustment feature is available for **AAPS** version 2.2 onwards.
88
+
* Howeever, the fully closed Loop will be deactivated for 3 hours AFTER the DST switch (usually 1am onwards) has taken place and **AAPS** will default to background basal as selected in your **Profile**.
89
+
This is done for safety reasons - **IOB** may be too high due to duplicated bolus prior to DST change.
90
+
* After DST has taken place, select **Profile Switch** to user's desired **Profile** to enable fully closed Loop.
91
+
* You will also receive a notification on **AAPS** main screen prior to DST change that the Fully Closed Loop has been disabled temporarily. This message will appear without beep, vibration or anything.**
92
+
93
+
94
+
If you bolus with **AAPS'** calculator please do not use **COB** and **IOB** data unless you are sure this data is absolutely correct. Take caution and do not use this feature for a couple of hours after DST switch has taken place.

107
+
* Otherwise, if you do not want **AAPS** to temporarily default to background basal overnight, you can change the time zone the day prior DST is due to take place to avoid overnight disruption. NOTE THIS OPTION MAY CAUSE YOUR POD TO PREMATURELY EXPIRE. PLEASE HAVE SUPPLIES WITH YOU IF OPTING FOR THE FEATURE BELOW.
108
+
109
+
#### Actions to take before the clock change
110
+
1. Switch OFF any Phone's settings that automatically sets the Phone's time zone, so the user can change to a time zone that does not use DST. How to enable this will depend on your smartphone and Android version.
111
+
112
+
* Some phones have two settings, one for automatic setting of the time (which ideally should remain on) and one for automatic setting of the time zone (which you must turn OFF).
113
+
* Unfortunately, some Android versions have a single switch to enable automatic setting of both the time and the timezone. You’ll have to turn this off for now.
Depending on pump and CGM setup, jumps in time can lead to problems. With the Combo e.g. the pump history gets read again and it would lead to duplicate entries. So please do the adjustment while awake and not during the night.
