Php mktime() vs date()

Question

This is a PHP question. When I test this code

echo date("d-m-y h:i:S");

on my local server and on my hosted website (these two have different time zones) they return different datetime values,as expected. But when I try this code

echo mktime();

I see the same result on both servers.Does mktime() return the number of seconds from 1970 for a standard time zone,whatever your timezone is?

Thanks for your answers

Answer 1

From the documentation:

mktime — Get Unix timestamp for a date

Synthesizing this with your initial question:

Does mktime() return the number of seconds from 1970 for a standard time zone,whatever your timezone is?

yep.

Answer 2

mktime() returns the Unix timestamp corresponding to the arguments given. This timestamp is a long integer containing the number of seconds between the Unix Epoch (January 1 1970 00:00:00 GMT) and the time specified.

date() returns a string formatted according to the given format string using the given integer timestamp or the current time (local timezone) if no timestamp is given.

Answer 3

As the documentation mentions mktime() returns the seconds from begin of the epoch in GMT time while date() (without the second argument) returns the time in the local timezone.
