Bug report: 1970-01-01 problem

Hi there, I’d like to report a bug in the current version of WooCommerce.

Here is how to reproduce it.

Take a product on sale with variations.

Then with the drop-down bulk actions menu select the option to set up start and end dates for the sale (for all variations of the product).

Let’s set up a start date 2024-02-02 and leave the end date empty.

In that case, no date should appear in the end date field (only YYYY-MM-DD). In the current version, however, 1970-01-01 appears instead, thus cancelling the sale immediatly. The solution is to set up any date in the far future to make it possible the sale to appear on the frontside.

I have tested on Woo ver. 8.2.1 and 8.5.2

On 8.2.1 version YYYY-MM-DD appeared, on 8.5.2 – 1970-01-01.

It’s a small but annoying bug which will be nice to get rid of.

Tested on various sites, themes and plugins.
