We can change the date when click the page date ( below the page tilte ). But we cannot change the full time when we click the page time.
Gem for OneNote v17 now provided the change full page date time feature.
- Current Date button: replace the page date with current date.
- Current Time button: replace the page time with current time.
- Now button: replace the page date & time with current date & time.
Finally, click the "OK" to modify the page date & time.
