When using the date picker, the date I select gets reported one day earlier

At title says, my template works as expected except for the date picker. If I use the calendar pop-up and select 24 June, when the template is created the date displays 23 June. Same behavior if I type the date in or select from UI calendar. Even if I select "Today" the note that gets created shows yesterday's date.

Any idea why this is happening? Locale or time zone issue? I've using various times for the tests, and the times are displayed correctly.

I am fairly certain my computer clock and the date on my watch are not one day ahead. ;)

Reproduce the issue in the Templates plugin on Windows by selecting and typing dates in the template date picker, including Today. Trace the date value from the picker through template creation and verify that the created note preserves the selected calendar date rather than displaying the previous day.
