Note: I posted this question to the newsgroup as well. I'm not sure which is the more appropriate forum.
Is there a way to get string variable that is equivalent to the output of the disp method for a datetime object, which is written to the command line interface? I'd like to print formatted strings from datetime arrays to a file, but fprintf says that it is not defined for datetime inputs.

The way to convert a datetime into a string according to the datetime Format attribute is actually very simple: Use char
d = datetime;
s1 = char(d)
d.Format = 'uuuu-MM-dd''T''HH:mm:ss';
s2 = char(d)
The documentation of datetime (accessed through doc datetime) is actually not very good as it does not tell you all the methods of the datetime object. However you can see all of them with
help datetime

Bruce, in your C.S-S.M post, you said, "write data and labels to a file". It's worth noting that if you have everything in a table, writetable will automatically write out the datetimes to the file with no conversion necessary. It uses the format and the timezone that the datetime variable in the table is set to, so if you want both a local and a UTC timestamp in the file, you'd have to have two datetime variables in the table.
