CSDK supports multiple device connection (MDC) and POS system. Card readers and CSDK installations can be set up at different places with different time zones and their time/date should be set to different value because of time zone difference.

 This feature is only available for CWS/C#/Android.

### C\#

```c#
string timeZone; // example US_EAST, CA_PACIFIC, ...
 
// Asynchronous

## Implementation 

### C\#

```c#

 cwsevent.deviceSerialNumber, cwsevent.statusDetails, local.ToString(), cwsevent.chanId));
 if (!String.IsNullOrEmpty(cwsevent.chanId))
 {
 m_ChanId = cwsevent.chanId;
 }
 }
}
 
// Set Time zone callbacks
public void MySetTimeZoneOnCardReaderComplete(SetTimeZoneOnCardReaderResults rsr)
{
 Log("----------- SetTimeZoneOnCardReader Complete ------------");
 if (rsr != null)
 {
 Log(String.Format("Status: {0}", rsr.StatusDetails));
 Log(String.Format("Completed: {0}", rsr.Completed));
 }
 else
 {
 Log("NULL RESULT");
 }
}
 
// m_CWS is an instance of CWS instantiated earlier
// timeZone is a string and the supported values are
// A_ATLANTIC, CA_EAST, US_EAST, US_INDIANA_EASTERN, US_MICHIGAN, CA_CENTRAL, US_CENTRAL, CA_MOUNTAIN, US_MOUNTAIN, CA_YUKON, US_ARIZONA, CA_PACIFIC, US_PACIFIC, US_ALASKA, US_HAWAII.
m_CWS.StartSetTimeZoneOnCardReader(timeZone, ne, completionDelegate);
```

### Java (Android)

```java

}
 
// The following codes are copied from MainActivity.java of the sample application// cardReaderInterface is an instance of ECLCardReaderInterface and should be obtained earlier through CSDK initialization
cardReaderInterface.updateTimeZone(timezone, new ECLCardReaderSetTimeZoneOffsetFromUTCListener()
{
 @Override public void deviceOperationCompleted(ECLCardReaderInterface eclCardReaderInterface, ECLTransactionProgress eclTransactionProgress)
