datetime.hms
datetime: [h, m, s] = hms (T)
Hour, Minute, and Second components of a datetime array.
[h, m, s] = hms (T) returns the hour,
minute, and second components of the corresponding datetime values in
T as separate numeric arrays. h and m contain integer
values and s may also contain a fractional part. All outputs have
the same size as T. Not-A-Time (NaT) values in T are
returned as NaN in the output arrays.
