[QUESTION] Why is the data timestamp obtained by the OpenDAQ Client different from the timestamp provided by the OpenDAQ Server?

### Question

Dear, OpenDAQ Team
      I encountered a problem while using Open DAQ and I hope to get your assistance.
      We have developed a data acquisition device based on OpenDAQ. Multiple devices synchronize their times using PTP1588 and can trigger multiple channels of multiple devices to start data acquisition simultaneously based on the device time.
     Now, we are encountering a problem with the simultaneous triggering of data acquisition. The multiple channels of the devices do indeed start data acquisition almost simultaneously. For example, for 4 channels within one device, the timestamp of the first sampling point is relatively close. However, when the data is uploaded to the PC, the timestamps read from the OpenDAQ Client test program on the PC sometimes do not match the timestamps reported by the device. This occurs occasionally. Restarting the OpenDAQ Server on the device side may restore the normal operation. When the problem occurs, closing the channels and triggering again still shows the same phenomenon.

Below are the key codes for the Server side, namely ref_channel_impl.cpp
`void RefChannelImpl::collectSamples(std::chrono::microseconds curTime, bool discard)
{
    //auto lock = this->getAcquisitionLock();
    if (!acqActive || !sampleStart)
    {
        return;
    }

	bool debug = false;

  uint64_t newSamples = 0;

	const int64_t intervalUs = (curTime - lastLogTime).count();
	//Print every 20 seconds， for debug.
	if (intervalUs >= 1000000*20) 
	{
		debug = true;
		lastLogTime = curTime;
	}

    int ret = sdaq_get_sample_remain(index);
    if (ret < align)
    {
        newSamples = 0;

		if (ret < 0)
		{
			LOG_E("sdaq_get_sample_remain ret:{} {}", ret, sdaq_get_err_string());

    		{
				LOG_W("collectSamples deltaT:{} time:{} start:{} samplesGenerated:{} DiffUs:{} diffMax:{} ret:{}", deltaT, curTime.count(), startTime.count(), samplesGenerated, readDiff, readDiffMax, ret);
	    	}
			remainPre = ret;
		}
    }
	else
	{
		newSamples = sdaq_byte_to_sample_count(index, ret, shift);	
	}
	 readDiff = (curTime - lastCollectTime).count();

Below is the Client test code for the PC side (Code description: Configure external triggering for all channels, configure channel enablement. Then configure the device trigger, trigger at a specified time, wait for the trigger, read the sampling data, and check if the timestamp of the first sampling point is close to the specified triggering time. The SampleDataProcess function reads the data to check the timestamp of the first sampling point. The AutoTestProcess function controls the loop for configuring triggering, stopping triggering, and sampling.)

By comparing the log screenshots, it can be seen that for ch0 and ch3, the sampling timestamps and the first four sampled data are the same for both Server and Client. For ch1 and ch2, the sampling timestamps are different for Server and Client, but the values are the same. The sampling data timestamps for ch1 and ch2 are incorrect.
Could you please advise me on how to proceed with the analysis? I would like to know if there is an error in the timestamp of the data frames sent by the socket, and determine in which module the timestamp is changed. However, I am not familiar with the internal processing mechanism of OpenDAQ and would appreciate guidance from the OpenDAQ team.

Below is the complete log of the PC test program.
