new DateTime('2016-04-01 00:00:00') returns '2016-04-01 12:00:00

This is probably a no-brainer, but I can't see the solution. I have the following code:

$begin = new DateTime('2016-03-14 00:00:00');
echo $begin->format('Y-m-d h:i:s');

The output is:

2016-03-14 12:00:00

I have tried to change timezones, set the timezone, leave it off. The output never changes. What gives? I want the output to read "2016-03-14 00:00:00".

h is for 12-hour clock (AM/PM), so your pattern lacks a or A to be complete:

$begin = new DateTime('2016-03-14 00:00:00');
echo $begin->format('Y-m-d H:i:s a');

would give you 2016-04-01 12:00:00 am.

If you want full 24-hrs clock, you need to use H instead:

$begin = new DateTime('2016-03-14 00:00:00');
echo $begin->format('Y-m-d H:i:s');

which would give expected 2016-04-01 00:00:00.

Here is the documentation for supported placeholders you can use with format().

As said, h is for 12-hour clock format , and H for 24-hour clock format. By changing this letter, your date will format as you wish.

$begin = new DateTime('2016-03-14 00:00:00');
echo $begin->format('Y-m-d H:i:s');

You need to use H as it is for 24 hour time and h is 12 hour time. 12:00:00 is 12am or 00:00:00:

$begin = new DateTime('2016-03-14 00:00:00');
echo $begin->format('Y-m-d H:i:s');

It should be

$begin = new DateTime('2016-03-14 00:00:00');
echo $begin->format('Y-m-d H:i:s');

h 12-hour format of an hour with leading zeros 01 through 12

H 24-hour format of an hour with leading zeros 00 through 23
