	613	+=== 2.6.2 Set Device Time ===
	614	+
	615	+There are two ways to set the device's time:
	616	+
	617	+
	618	+(% style="color:blue" %)**1. Through LoRaWAN MAC Command (Default settings)**
	619	+
	620	+Users need to set SYNCMOD=1 to enable sync time via the MAC command.
	621	+
	622	+Once CPL01 Joined the LoRaWAN network, it will send the MAC command (DeviceTimeReq) and the server will reply with (DeviceTimeAns) to send the current time to CPL01. If CPL01 fails to get the time from the server, CPL01 will use the internal time and wait for the next time request ~[[[via Device Status (FPORT=5)>>url:http://wiki.dragino.com/xwiki/bin/view/Main/User%20Manual%20for%20LoRaWAN%20End%20Nodes/CPL01%20LoRaWAN%20Outdoor%20PulseContact%20%20Sensor%20Manual/#H2.3.1DeviceStatus2CFPORT3D5]]].
	623	+
	624	+
	625	+(% style="color:red" %)**Note: LoRaWAN Server needs to support LoRaWAN v1.0.3(MAC v1.0.3) or higher to support this MAC command feature.**
	626	+
	627	+
	628	+(% style="color:blue" %)** 2. Manually Set Time**
	629	+
	630	+Users need to set SYNCMOD=0 to manual time, otherwise, the user set time will be overwritten by the time set by the server.

	634	+
	635	+Users can poll sensor values based on timestamps. Below is the downlink command.

	651	+Timestamp start and Timestamp end-use Unix TimeStamp format as mentioned above. Devices will reply with all data logs during this period, using the uplink interval.
