DateTime need support for UTC time as opposed to local browser time

[smesdaghi]

When editing events especially historically significant dates, using the feature edit displays the datetime in local time zone set in the browser. this means if an event took place in 2am 1-1-1990 it can show as 12-30-1980 10pm.

if someone is editing a feature to correct the date, they have to adjust for their local time zone so that the time is correct when people in other timezones view the data and even then, they have to adjust the datetime to know the utc time.

perhaps a toggle next to date field in attrib edit to show as utc?
