If you happened to use FAT/FAT32 or another file system with severely limited timestamp range, then that warning is to be expected.

Symfony's FilesystemCommonTrait::write() method calls touch() function with unix timestamp 0 to force expire cached content. Unix timestamp 0 represents 1970-01-01 date. In FAT file system the allowed timestamp range is 1980-01-01 to 2099-12-31, according Wikipedia. So the touch() function fails and a warning is issued.

The workaround is to modify the FilesystemCommonTrait::write() method, around line 80.

Find lines:

if (null !== $expiresAt) {
    touch($this->tmp, $expiresAt);
}

Insert before those lines:

if (0 === $expiresAt) {
    $expiresAt = time() - 1;
}

This should achieve virtually the same result by instantly expiring the cached content, but without using an invalid file system timestamp.

Alternatively, change the file system type.
