Analysis error with input timetables

Why I am getting error:
Error using timetable/retime
All variables in input timetables must be numeric, datetime, or duration when synchronizing using 'mean'.
Error in ko - 1h avg to new channel (line 10)
avgdata=retime(data,'regular','mean','TimeStep',hours(hourz));
DATA EXPORT CSV LOOKS LIKE:
2023-01-21T23:47:13+02:00 45161 533 23.187 29.27 18.23 18.61 -8.5 93 -10
CODE ko - 1h avg:
dayz=1;
hourz=1;
rc=1234;
rk='KEY';
wc=5678;
wk='KEY';
data=thingSpeakRead(rc,'ReadKey',rk,'OutputFormat','timetable','numDays',dayz);
avgdata=retime(data,'regular','mean','TimeStep',hours(hourz));
thingSpeakWrite(wc,avgdata,'WriteKey',wk);

The T is the main problem. The default formats do not support the time zone offset field but you can specify XXX as an input format to code for that. There is no direct code for the T however. You have to code 'T' for that where the apostrophes are part of the syntax. For example "uuuu-MM-dd'T'HH:mm:ssxxx"
Notice the use of " to make it easier to code the literal ' characters
