string for figure title ignores text after variable

I have the following code while creating a figure:
titlestr=sprintf('Time=%6.5f',t(1), 'sec');
title(titlestr);
No error is generated but Matlab won't print the word "sec" after the time, t(1). This code is part of a video so that the user can see the time increasing as Matlab executes code. I'm just trying to put the word "sec" after the time so that viewers know that the time is in seconds and not minutes or hours, etc.

Write it as one string, with the variable in the midst of it"
t = 8.2;
titlestr=sprintf('Time=%6.5f sec',t(1));
title(titlestr);
