varfun applied to table not recognising equal values

1 view (last 30 days)
I have 3 tables with two columns of time (intervals of 10minutes) and speed. The time column is in datetime format. I have stacked the three tables on top of each other and assigned valiables a and b to the new time and speed columns, respecivetly.
Then I used:
x=varfun(@mean,TT,'GroupingVariable','Date & Time')
However the function doesn't seem to recognise Dates & Times that are equal so in x, for example, there are say two 31May2010 15:10 rows.
Oddly, After this date/time the same thing happend for every xx:10 and xx:40 time.
How do I fix this?

Are you sure the values are equal? They could be displayed as the same value without the stored value being the same.
dt1 = datetime('now')
dt1 = datetime
10-Dec-2020 19:46:58
dt2 = dt1 + seconds(0.001)
dt2 = datetime
10-Dec-2020 19:46:58
dt1 == dt2 % false
ans = logical
dt2 - dt1
ans = duration
ans = 1.0000e-03
