Please change the number of seconds to the question of small hours

Ask the number of seconds to change to a small time problem

This is the 06:00:00, according to the truth is 30 hours, and this is correct, is 20 hours


Blue in the admin reply is:
“
Gmstrftime returns a Greenwich mean GMT.
The first one is 30 hours, minus 24 hours a day, that's 6 hours.
The second one is 20 hours, within a day, so it is correct.
This function, not for the second to the number of hours, less than 24 hours, still can barely

”


Finally, how to convert to less than 30 hours of time? For example, I have a number of seconds to 1080000, how to get 30:00:00 Thank you

------Solution--------------------
You can work it out.
$t = 108000;
echo Floor ($t/3600). Gmstrftime (':%m:%s ', $t);//30:00:00
