Time Field Inserting a Blank Space

Temporary patch to remove prefix as per #3 attached.

I'm not seeing this with PHP 8.1, Drupal 7.94, Date 7.x-2.14. Could it somehow be related to the PHP version?

It might be worth adding a widget setting to control this.

I ran into this. Clicking the time field input adds a space before am/pm. if the "accepted format" on the field doesn't have a space, then it will fail.

A workaround:
The accepted format is configurable on the date field under "Date entry options". The default formats in that dropdown do not have a space before am/pm. But you can add your own format options to that dropdown under: /admin/config/regional/date-time/formats. E.g. Add a new format with a space before am/pm "M d, Y - g:i a". Then set this as your "accepted format" on the field.

Workaround in #8 worked for me - thanks!

The patch in #3 and #4 fixed the problem right up. Hopefully the next version can come out soon to save a lot of headaches, esp. for the less techie. Thanks for everyone's work.

Just chiming in. Patch in #5 fixed me right up. Thanks!

Patch in #5 fixed the issue for me too.

Patch #5 fixed it for me too.

Workaround in #8 worked for me too - thanks @jayemel

Pushing it back to NW based on maintainer feedback in #7, though I am not 100% sure if this really needed?
