That information on those links are what we call the "Released" dates, which typically differ from the "Published" dates found in the physical comics actual indicium by about two months, though that varies from publisher to publisher.
You can usually find previews of the issues on various websites shortly before they come out that have the first couple pages, that's how I found the first seven for Spidey's, but it's more difficult with these IDW series than typical Marvel issues since they're not as widely covered by sites as other series are and they don't have digital release.
They're still currently under TRN240 and there character pages are separate from their 616 selves so when something is referring to the TRN240 characters and you alter the links to refer to the 616 versions (even if you state it's the time displaced versions) instead it makes it somewhat incorrect and makes their TRN240 pages harder for people to find/accredit to them
I understand your reasoning, but by the end of Extermination Vol 1 5, it has been proven that the TRN240 characters are actually in fact, their 616 counterparts from the past, and it has been discussed that any appearances the time-displaced team should be changed.
I haven't seen any discussion like that but the pages for the TRN240 characters still remain so shouldn't events directly relating to them and referenced on their pages still direct to them, rather than to their 616 counterparts whose pages lack that information, until the pages are merged or their information is altered to include those events and when that happens it will most likely be done by a bot
I've looked at them and seen your suggestion for what to do on them but the admins have made no actual concrete decision on what to do so I'd say leave them as they are cause there are over 3,200 articles mentioning them and unless you can completely alter all of those in a consistent manner in a matter of days so the information stays accurate, have the admin's approval to do it and have the pages they link to properly reflect what they're referring to you're just going to end with content that links to incorrect sources/sources that don't include the content they're supposed to be linking to. You can keep an eye on it but like I said from what I can see no decision has been made on how to incorporate it properly and when it is made an admin/mod or something will most likely be charged with taking care of it.
We're in the process of merging them, but there's several thousand links associated with the time-displaced original five, so 1137a has been helping me manually add some of the necessary green text, as well as checking for contradictory levels of appearance regarding their present selves within the same issues, all of which is required before the bot can handle the rest.
