Use the years, days, minutes, and seconds functions to create datetime and duration sequences
using other fixed-length date and time units. Create a sequence of duration values between 0 and 3
minutes, incremented by 30 seconds.
d = 0:seconds(30):minutes(3)
d = 1x7 duration

30 sec
60 sec

Compare Fixed-Length Duration and Calendar Duration Step Sizes
Assign a time zone to t1 and t2. In the America/New_York time zone, t1 now occurs just before a
daylight saving time change.
t1.TimeZone = 'America/New_York';
t2.TimeZone = 'America/New_York';
If you create the sequence using a step size of one calendar day, then the difference between
successive datetime values is not always 24 hours.
t = t1:t2;
dt = diff(t)
dt = 1x4 duration

Create a sequence of datetime values spaced one fixed-length day apart,
t = t1:days(1):t2
t = 1x5 datetime

Integer Step Size
If you specify a step size in terms of an integer, it is interpreted as a number of 24-hour days.
t = t1:1:t2
