Each Diary Entry is timestamped with a unique Entry Date that defaults to the current date/time. Often, you may want to adjust that time, and this is the purpose of the Timestamp Editor. Using the editor, you can select the necessary date and time for the Diary Entry.
The currently selected timestamp is shown in the Title Bar and on the Date/Time Picker control. By default, the control offers time selections on the quarter hour. This can be changed in the application settings if you wish to specify your Diary Entries to a more granular time period.
This button is a convenience tool which will reset the Date Picker control back to the current date/time.
