Time

Time is measurement of intervals in which actions take place. In Crawl, time has multiple definitions:

• Action Time: Every action ingame is measured in aut, or arbitrary units of time. Certain actions may be faster or slower relative to each other; you could perform 2 fast actions in the span of one slow one. This is what the "Time" counter in the status screen is measuring.
• Turns: Every command uses up 1 turn, no matter if it was fast or slow (keybinds like autoexplore are macros that input multiple commands at once). This is used for a few game mechanics (such as stealth), is the main component in determining high scores, and the focus of a turncount speedrun. Turn count can be viewed in the % screen.
• Clock Time: How long, in minutes and hours, a game has been running. This is recorded ingame and is measured for realtime speedruns, but the game will not naturally progress through turns no matter how much the player waits. Clock time can also be viewed in the % screen.
• System Time: The real life time of day, according to the computer/server you're playing on, which progresses even if the game is off. Ingame, this is used for a singular cosmetic player title for Meteorae. Outside of it, system time is obviously used for various discussions relating to the outside world (when was a game played? and such).
