- blinky lights and numbers
- display options for 12- or 24-hour, UTC or local, seconds & tenths
- NTP accuracy
- leap second display
- optional tick sounds
- optional screen brightness control

(Requires Internet access. Emerald Time does not change the internal clock used by all other iPhone apps.)
