Have you tried setting the timezone via the php prescribed function:

date_default_timezone_set() ?

same output with the following code:

date_default_timezone_set("UTC");

foreach (range(-63158410,-63158390) as $s) {
echo $s.': '.date("d-m-Y H:i:s (T)",$s)."<br>";
}


Shouldn't this work regardless of the timezone? How can we have a
'disappearing' day?

The DST offset could move you to the next day, you may want to try to
pick 6-7 am on the 1st of Jan 1968 to see if that works.

same output with the following code:

date_default_timezone_set("UTC");

foreach (range(-63158410,-63158390) as $s) {
echo $s.': '.date("d-m-Y H:i:s (T)",$s)."<br>";

Shouldn't this work regardless of the timezone? How can we have a

Yes, this seems to be a windows-only problem. I've tested it on Linux
and it works as expected.
Regarding DST, I'm no expert on this matter, but DST could probably
'bump' time one hour forwards or backwards, not lose a whole day. As
for testing 6-7 AM, I wasn't able to target any hours in 01-01-1968.

Portugal didn't do DST between 1966 and 1976, so that is not the issue.
I'll have to see what I get on Windows once that POS wants to boot again
