The game often refers to time periods in seconds, minutes, hours or days. These times are close to, but slightly longer than, real life time. These slightly longer time periods are called TeppyTime. The exact difference varies with many unpredictable and hard to measure factors (such as game server load), but tends to average about 11.1 to 11.5 real-life seconds per 10 TeppySecond.
The /ts command switches on a display of age timestamps for each line of text in all chat channels. These timestamps are in TeppyTime, and so are synchronised with the durations of in-game events.
The /time command displays an "Egyptian" time. Egypt time passes at a rate of 3 Egypt minutes per TeppyMinute, and so roughly 2.7 Egypt minutes per real minute. The /clock and /clockloc commands show this time in a small window.
Research countdowns are also in TeppyTime; the normal 24-hour countdown is about 27 hours of real time.
Endurance and focus (dowsing) timers, and forge and casting box times, are all in TeppyTime.
Beer kettles have a countdown timer in seconds for adding ingredients and fermenting; these are really TeppySeconds. As such, they provide the most fine-grained way to synchronise actions with the in-game timers. However, each building has it's own clock, and so a kettle can also get out of sync with another building (such as a glazier's bench).
