Generated Media Path Wrong by Timestamp?

Hello all,
We are currently carrying out a media import. Everything runs great and locally (Dockware) everything worked perfectly.

Unfortunately, however, our image path on our server deviates from a single timestamp:
Generated Url: shopurl/media/90/8a/1a/ 1645794409 /89992T.jpg
Existing image path: shopurl/media/90/8a/1a/ 1645790809 /89992T.jpg

As you can see, the last folder is generated with a timestamp that hangs 1h behind.

We already have tried
SHOPWARE_CDN_STRATEGY_DEFAULT=„id“
SHOPWARE_CDN_STRATEGY_DEFAULT=„filename“
and
SHOPWARE_CDN_STRATEGY_DEFAULT=physical_filename

Also tried with var/cache clear etc without success.

It seems like the timestamp is exactly one time zone behind.

I would be grateful for any help.
