Details:

Create a datevec series of dates and times, spaced by 20 minutes, with the
minutes column values being exactly 0, 20 and 40 with a given starting and
ending time in datevec format. 

First create a typical 20 minute datenum difference value

datenum_20_min_diff=datenum([2021,1,27,17,0,0])-datenum([2021,1,27,16,40,0]);


Next, create a sequence of datenums, spaced by datenum_20_min_diff, from one
given datevec to another datevec and display output as a datevec, e.g.


datevec((datenum([2021,1,27,22,0,0]):datenum_20_min_diff:datenum([2021,1,28,11,0,0]))')


gives unexpectedly formatted output in stout. After a few lines the minutes
and seconds columns of the datevec output display e.g. 59 and 60 respectively,
instead of the expected 0 and 0.
