Retime function creates new rowtimes going back to 1899

3 visualizzazioni (ultimi 30 giorni)
I have a timetable of data that I am trying to average to two minutes. When I use:
CO2_TT = retime(CO2_TT,'regular','mean','TimeStep',minutes(2));
It creates new row times going back to the year 1899. I've not seen this happen before and I use retime everyday. I have another timetable in the workspace that does not have this error. What would trigger this?
load CO2_TT.mat
CO2_TT = retime(CO2_TT,'regular','mean','TimeStep',minutes(2));

You have a few dates from 1899 in your input data
load CO2_TT.mat
[minDateTime,indexToMinDatetime] = min(CO2_TT.DateTime)
minDateTime = datetime
31-Dec-1899
indexToMinDatetime = 649
CO2_TT(CO2_TT.DateTime==min(CO2_TT.DateTime),:)
ans = 3×11 timetable
