Calculate std with retime function

Hello,

I have a timetable tab20sel vith 4 variables Var1-Var4 (wind velocity components and temperature), sampled at 10 Hz, first four rows:

'2017-10-28 08:00:00.000' 9.0600 2.1200 -0.5900 8.4100

'2017-10-28 08:00:00.100' 8.2800 2.5100 -0.3900 8.4200

'2017-10-28 08:00:00.200' 8.2600 2.4400 0.0600 8.6800

'2017-10-28 08:00:00.300' 8.1700 2.7200 -0.1700 8.4700

I would like to calculate the standard deviation of all four variables in 10-minute interval with retime function:

newtimestep=minutes(10);
tab20retstd=retime(tab20sel,newtimestep,@std);

but I get an error which I dont understand:

Error using timetable/retime

All input timetables must have row times with the same data type as target time vector.

Neither this code doesnt work:

tab20retstd=retime(tab20sel,newtimestep,@(v)std(v,[],1));

What am I doing wrong? Thanks.

I have already found a working code:

tab20stdret=retime(tab20sel,'regular',@std,'TimeStep',newtimestep);
