Wrong dates after syncing photos

Most of us don't have much experience transferring pictures with iTunes on a PC, and I'm surprised the dates are messed up. Transferring pictures from computer to phone may have other ill effects-- have you checked to see if the pictures you've transferred can be edited? If not, then pictures there are not fully controlled by Photos, and they may be at some risk.

Another option is to use iCloud. You could buy 200 GB of iCloud, $3 for a month, transfer your pictures there using a browser, let the iPhone's Photos download them, and then cancel iCloud. With an iPhone you get 5GB of iCloud free, so you could try it with a few pictures and see if it worked for you before doing 7000 pictures. Since I use a Mac, I don't load pictures that way, but I think that you are limited to 1000 at a time, perhaps to avoid tying up the servers.

I am trying to sync a photo album that I have on PC to my iPhone using the method "Sync photos in iTunes on PC with devices". I'm trying to sync a album and I can see on my PC that each photo has the correct date and time, however, when synced to my iPhone all photos are suddenly from the same date (Yesterday 7pm).

Make sure you are looking at the EXIF "DateTimeOriginal" metadata date on the PC (*), NOT any file dates or other system dates which are often reverted to the current date when moving images to different devices. Also notice that many social media sites like Facebook and WhatsApp delete internal EXIF metadata dates so those fragile file dates are used as a last resort.

(*) Notice that in Windows, "Date Taken" field might be ambiguous. Usually it corresponds to the EXIF DateTimeOriginal for most image files. If DateTimeOriginal is missing, Windows may fall back to display many other EXIF/XMP/IPTC metadata tags as "Date Taken" instead.
