Page schedule Start and End dates change after saving

[daguiler]

Description of bug

In the Pages panel, if the "Enable Scheduling" switch is on, a start and/or end dates are set, the page is saved and then the page is refreshed, the start/end dates will show different than the originally specified. Dates will be off depending on the user TZ. In my case they look 3 hours later because I'm on UTC-03.
If I set the correct date and save again, then it looks correct afterwards. It's the first time (when dates are still null) that fails.

Steps to reproduce

1. On DNN 9.6.2 open the Pages panel
2. Pick any page and turn the "Enable Scheduling" switch on
3. Specify a Start Date (at midnight, to make it easy to verify)
4. Save
5. Hit F5 to refresh the page and wait for the Pages panel to open
6. Select the same page and observe the Start Date

Current behavior

Unless you are at UTC timezone, the Start Date will be off by X number of hours where X is your TZ offset.

Expected behavior

Start Date should not change after saving.
