753 +== 2.14 Clock logging (Since firmware version v1.2.1) ==
754 +
755 +Sometimes when we deploy lots of end nodes in field. We want all sensors sample data at the same time, and upload these data together for analyze. In such case, we can use clock loging feature.
756 +
757 +We can use this command to set the start time of data recording and the time interval to meet the requirements of the specific collection time of data.
