By default the class of the <time> element is wp-block-latest-posts__post-date. That's the class that's styled in the CSS.

However. if I add a custom class foo, the class will be wp-block-latest-posts foo__post-date. That's because the parent <ul> class is changed to wp-block-latest-posts foo has-dates and it's just copied for <time>.

I don't think the class of the <time> should be changed when adding a custom class, because the class is already added to the parent <ul>.
