Add time to datetime format

26 次查看(过去 30 天)
Hi,
I have a datetime format in the following format (MM-dd-yyyy), but it does not have time. How can I add time to it for instance 00:00 (midnight) so I get the format MM-dd-yyyy HH:mm:ss.

Try this:
de = ['08/21/2020 (Aug)'; '09/21/2020 (Sep)']
DT = datenum(de, 'mm/dd/yyyy')
DS = datestr([DT + zeros(size(DT,1),1)], 'mm/dd/yyyy HH:MM:SS')
producing:
DS =
2×19 char array
'08/21/2020 00:00:00'
'09/21/2020 00:00:00'
or alternatively just.
DS = datestr(DT, 'mm/dd/yyyy HH:MM:SS')
producing the same result.
.

A datetime array generally has a time component, even if it's not shown[*].
>> dt = datetime('today')
dt =
datetime
23-Aug-2020
>> dt.Format = 'dd-MMM-yyyy hh:mm:ss a'
dt =
datetime
23-Aug-2020 12:00:00 AM
[*] From the documentation for datetime: "Datetime values later than 144683 years CE or before 140743 BCE display only the year numbers, regardless of the specified Format value."
