It sounds like you've stumbled over behavior of Edit Capture Time that confuses many people. When you've selected multiple photos, the time of the most-selected one is set to the time you enter, and the time of the others is adjusted by the same incremental difference. The fine print in the Edit Capture Time window explains this:
So the selected photos won't all be set to the same time. See this article for a more complete explanation: The time on my camera was incorrect—how do I change the capture time? - The Lightroom Queen
I wish I could change the capture date/time and choose the increments of date/time from one photo to the next.
The Capture Time To Exif plugin lets you do that. (As you've discovered the ExifMeta plugin is no longer available.)
Thank you for that response. ... Yes, I did figure out that out. The problem is that I want to be able to determine the incremental difference between each photo. Since the original times/dates are either very wrong or missing, the increments have no rhyme or reason after I make the update.
Thank you so much for the plug in! I will try it tonight :-)
I have finally had a moment to download the plugin. Thank you! I followed the install instructions and I see that it's enabled. But when I go to library > plug-in extras, "jb to CaptureTime to Exif" is greyed out and not an option. Do I need to buy it and get a registration code?
Thank you for your helpful advice,

Make sure you have one or more photos selected before invoking the command.
I believe the plugin will run during a free-trial period, perhaps on limited numbers of photos. So you shouldn't have to buy a licence to try it.
I did have multiple photos selected (I tried one photo as well) and it still doesn't work. I just emailed the developer. I'll let you know what I hear :-)
As I replied:
"The plugin is in trial mode until you buy and enter the licence number. What you are probably overlooking is that the greyed-out menu is Adobe’s misleading way of showing the plugin name, and that its submenus are the plugin’s actual menu items."
It was misleading. I see it now. Thank you :-)
So I'm a very novice user, so this could certainly be user error. But when I change the date and time using the plugin, I have the same issues I had with LR (doesn't update dates correctly, most photos still don't have any dates, etc.). Do I need to buy the plugin for the date/time change to work on multiple photos? I'm so happy to as long as I know it will work.
I suggest you check all your cameras to make sure they have the correct time and date so you don't have to go through this again.
Of course.I did that years ago. But many dates/times have been lost in translation when moving. I'm guessing there are about 2 years of photos that have incorrect times, not to mention scanned photos from before digital photos. If you read the first part of my post... "The original photos were stored in iPhoto for many years with the incorrect capture dates/times (I didn't have the date/time set properly on my camera for a long time). iphoto is terrible, so I found Lightroom as a better solution. The process of moving the photos from iPhoto to LR was messy to say the least (three computers are involved and two external drives), thus the incorrect capture dates/times were lost." So I'm still trying to figure out how to fix old photos.
When I change the date and time using the plugin, I have the same issues I had with LR (doesn't update dates correctly, most photos still don't have any dates, etc.)
After invoking the plugin, make sure you do step 4:
Use Library's Metadata > Read metadata from file command to update Lightroom
That will read the metadata changed by the plugin (the capture date) back into LR. (Older versions of LR don't provide plugins with any way of doing that.)
If this doesn't solve the issue, I'm sure the the plugin author (John B) will be able to help.
The problem people usually have is that they don't run the Metadata > Read Metadata which is critical to bring the dates back into Lr. It is mentioned in the instructions but you may have overlooked it.
The trial version is fully functional. It just limits how many images can be updated.
