David Nugent 658248453e Fix cosmetic bug in time display. Current day logins are now displayed
as plain time as originally intended, instead of displaying DayHH times
when the login time happens to be prior the GMT - TZ difference.
(Only noticable on systems operating east of GMT/UTC).
Local times are now used to determine the day.
