alchemy/zippy, Member::getLatsModifiedDate() return DateTime, not string

[rotdrop]

Hi there,

I think I stumbled over a bug here:

UnifiedArchive/src/Drivers/AlchemyZippy.php

Lines 232 to 233 in 5f02ad0

	$member = $this->getMember($fileName);
	return new ArchiveEntry($member->getLocation(), $member->getSize(), $member->getSize(), strtotime($member->getLastModifiedDate()), true);

At least in version 1.0 (the current since 2021) Member::getLastModifiedData() returns DateTime, not a textual representation of the last mtime. Hence strtotime() -- which expects a string -- fails. According to "git blame" this has always be the case(?) which surprises. I'll shortly submit a pull request.

Best
