Difference between two time values in minutes

I have two time point and was trying to calculate their difference to be converted to minutes.

t1 = 08/24/2010 13:21:47.030
t2 = 08/24/2010 14:13:09.118

I tried caldiff, duration, datetime and didn't work. Can you help?

dt = between(t1,t2,"minutes")

Do NOT use deprecated DATENUM or DATEVEC or DATESTR.

t1 = '08/24/2010 13:21:47.030';
t2 = '08/24/2010 14:13:09.118';
dt = datetime([t1;t2],'InputFormat','M/d/u H:m:s.SSS')

dt = 2×1 datetime array
   24-Aug-2010 13:21:47
   24-Aug-2010 14:13:09

d = dt(2)-dt(1)

d = duration
   00:51:22

m = minutes(d)

m = 51.3681

t1 = {'08/24/2010 13:21:47.030'};
t2 = {'08/24/2010 14:13:09.118'};
dt= diff(datenum([t1;t2]))*24*60

dt = 51.3681

% to get the second

second=diff(datenum([t1;t2]))*24*60*60

second = 3.0821e+03
