Howdy ponydesignclub,
You definitely could just hide the date/time from that box using a simple snippet that like this. However, the “meta group” you have chosen to override is very dynamic. If you want to set the value to simply be the date you are going to have to dive deep into our Meta Walker. The easiest way is probably to hide the field like I showed you above, then register a new field that returns just the date. If the last couple of sentences sound a bit like Greek, you might just want to go with the first and simplest option. Because the second option is going to require a bit of programming.
Does that make sense? Will one of those options work for you? Please let me know. Cheers!
