BUG#1
Given:

Attributes = Category, Status, Started, Finished, Activity, Headline
Type Started = date
Type Finished = date
Options Status = 1-To Do{1}, 2-Opened{2}, 3-Closed{3}, 4-Suspended{4}
{2} Preset Started = $date
{3} Preset Finished = $date
{4} Preset Finished = $date

There seems to be no setting of Date format (or Time format?) that gives a
meaningful value to attributes Started or Finished.  Even "Date format = %s"
- which gives number of seconds since 1970 - gives bad results.

BUG#2
In single entry view, elog returns an unformatted date value for "Type =
date" attributes - even when it has been manually entered with the date picker.
