- swatch .beat time
- binary clock
- counter-clock (runs backwards)
- % date
- % perl -e 'print time'
Me, I mostly just use the unix date command (to get the day of the week, mostly) or just check the time on my cell phone. A watch seems fairly pointless to me, given that I live in a place where there's a clock in every subway station, pay phone, or public square.
