GabayThe First Second of 2027 Takes 26 Hours to Arrive

SanggunianMilitary Time: What the Four Digits Actually Encode
Military time is not just the 24-hour clock written shorter. Fixed width, no separators, no AM/PM, and an optional zone letter — where each rule comes from, how to say it, and how a DTG packs a whole timestamp into 12 characters.
KasaysayanFrom Shadow to Atom: A History of Timekeeping

SanggunianUnix Timestamps: From 1970 to Now
One integer, fifty-six years, and a deadline in 2038. What Unix time actually counts, why the epoch moved three times before it landed on 1970, why leap seconds break the arithmetic, and which systems will not survive 19 January 2038.
