Description
The following code:
<?php
$date_fin = strtotime("2024-04-01") - strtotime("2024-03-31");
echo "date_fin=".$date_fin."\n";Resulted in this output:
date_fin=82800
But I expected this output instead:
date_fin=86400

A number of countries and timezones had a DST transition on March 31st, such as the one you're using. For them the day was, in fact, 82800 seconds long.

I don't know what you're trying to do but I expect that code there will be very, very incorrect.
Dates are hard. Might I suggest looking for help on StackOverflow or elsewhere?
