We need standard time during the summer and DST during the winter. This
would narrow the gap between nightfall in all seasons (while widening it in
the morning). So instead of sundown occuring at 8:30 PM in summer and at 4:30
PM in winter (a difference of 4 hours) it would occur at about 7:30 PM in
summer and 5:30 PM in winter (2 hour difference). On some summer nights it is
still light out till almost 9 PM. Who needs this ? As a consequence people
are at work during all daylight hours in winter. I think that this
contributes to seasonal affective disorder.
