I use an iPhone app called "Atomic Clock". It syncs with an NTP server of your choice, but it also has a particularly sharp "tick" on the seconds, and a different-toned tick at the top of the minute.

The clock also has an outer circle that can be configured to complete one rotation every second, which is great for comparing between clocks.
