Grab the following file from the File Exchange:
Then call:
x = 1263403529;
y = datestr(utc2datenum(x));

What is the use if Answer requires a specific environment like 64 or 32-bit. Can you simply change without source code?

You can do this using datetime.
>> dt = datetime(1263403529, 'ConvertFrom', 'posixtime')
dt =

If this is "seconds since 1970-01-01 00:00:00 TAI" it is more properly called "unix time" or "posix time" or sometimes "epoch time", not UTC. E.g., see this article:
If that is the case you can simply calculate your result as:
x = 1263403529;
e = datenum('01-jan-1970 00:00:00');
y = datestr(e+x/86400,'dd-mm-yyyy hh:mm:ss');

It's best to avoid string processing where it's not necessary:
e = datenum(1970,1,1,0,0,0);

Well, I would assume e would be a one-time only calculation in which case the string is more readable IMO. But if the goal is to make this calculation faster then I would simply eliminate it altogether. E.g.,
y = datestr(719529+x/86400,'dd-mmm-yyyy HH:MM:SS');
along with a comment stating where the magic number 719529 comes from.

Wrote my own utc2datenum and discovered that 'UTC' 1263403529 is NOT "13-Jan-2012 17:25:29" but 1326475529 is. I.e. datestr(utc2datenum(1263403529)) = 13-Jan-2010 17:25:29, hence differing 2 years, while datestr(utc2datenum(1326475529)) = 13-Jan-2012 17:25:29. Best thing is to check a routine or algorithm with the 'UTC' time example given on http://en.wikipedia.org/wiki/Unix_time instead of starting with a wrong example.

Current Wikipedia time is

utc =

perfect! Leave out the square brackets, and it works here too (R2015a 32 bit)
