CorrectLogTimes v1¶
Summary¶
This algorithm attempts to make the time series property logs start at the same time as the first time in the proton charge log.

string |
Experimental log values to be shifted. If empty, will attempt to shift all logs |
Description¶
Sometimes the clocks controlling different sample environments or other experimental log values are not synchronized. This algorithm attempts to make all (some) time series property logs start at the same time as the first time in the proton charge log. It uses ChangeLogTime.

w=Load('CNCS_7860')
run=w.getRun()
ts = np.datetime_as_string(run['proton_charge'].times[0].astype(np.dtype('M8[s]')), timezone='UTC')
print("Original start time for 'proton_charge': {}".format(ts).strip())
ts = np.datetime_as_string(run['Speed5'].times[0].astype(np.dtype('M8[s]')), timezone='UTC')
print("Original start time for 'Speed5': {}".format(ts).strip())
#Change the log times
CorrectLogTimes(w)
#there should be almost 10 seconds different than before
ts = np.datetime_as_string(run['Speed5'].times[0].astype(np.dtype('M8[s]')), timezone='UTC')
print("Corrected start time for 'Speed5': {}".format(ts).strip())
Output:
Original start time for 'proton_charge': 2010-03-25T16:08:37Z
Original start time for 'Speed5': 2010-03-25T16:09:27Z
Corrected start time for 'Speed5': 2010-03-25T16:08:37Z
