Hello,
Work is almost done, but there came one more problem: how can I converte the UNIX time to human readable format, like ISO086..
My UNIX time is in int64 format, for example: 1352434077. So when I tried to converte it with this code:
unix_epoch = datenum(1970,1,1,0,0,0);
for i=1:1:size(data_mat)
matlab_time(i,1) = data_mat(i,1)./86400 + unix_epoch;
end
It gave 735087..not something like YYYY-MM-DD: hh:mm:ss ...can anyone gave me a hint? Thanks a lot!

Take a look at datestr (or some of the other functions in the date-family):
datestr(matlab_time,'yyyymmddTHH:MM:SS')
or whatever format you might choose.

I guess you should do the typecasting to double ASAP, that is on the Data(1:10,1) before dividing by 86400 - as it is now that division will give you an int - and that corresponds to midnight since the time of day is in fractions of a day...
