"You're in America now," I said. "Our idea of diplomacy is showing up with a gun in one hand and a sandwich in the other and asking which you'd prefer."

LOADING HST TIME


The standard practice is to divide a day into the arbitrary units of hours, minutes, & seconds, of which there are 60, 1,440, & 86,400 respectively. In Holeman Simplified Time (HST), rather than having this hodgepodge you simply apply the principles of the metric system to time keeping. To do this, you simply divide a day into 100 equal parts; a centiday (sd) {Learn why it's sd rather than cd}. A centiday is 14.4 minutes long. Centidays are often pronounced "sid." I.e: "It's 50 sid" means that it is noon.

Any further granularity may be gained by using decimal places of a centiday. The standard is to use three decimal places. 1/1000th of a centiday is roughly equal to a second. There are 100,000 microdays (μd) in a day, compared to 86,400 seconds.) Microday are often pronounced "micks." I.e: "Just a mick" is the equivalent of "Hold on a sec."

In order to simplify timekeeping across the world, HST follows neither daylight savings time, nor bothers with time zones. 50 sd is the same moment in time if you are standing in London England, Huston Texas, or on the North Pole. The start of each day aligns with UTC.
