Why is there an error in hours when converting php time?

Question

PHP

There are dates in this form: 2018-12-26 14:24:12
To convert them to the desired format, I use

date ("d.m.Y h:i:s", strtotime('2018-12-26 14:24:12'))

And the result is: 12/26/2018 02:24:12 .
The question is why 14 hours turned into 02 and how to avoid this?

Answer 1

why 14 hours turned into 02

Because 14 hours is 2 hours in 12 hour format.
Specify 24 hour format. Replace h with H.
