Time can be the passage of time, clocks, sundials, time lapse, age, multiple exposures or sequences of a photo to show the progression of time, etc.
Direction can be GPS, maps, compass, trails or roads, tunnels, or integrate directional signage or arrows. You could also force yourself to photograph in a direction you have never used before: straight up, under, straight down, from a high vantage point, or while moving.
