AUTO follows the operating system. Working hours drive the green banding on every grid. All four persist on this device only.

CET to CST

CET is UTC+2 and CST is UTC−5 today — CST is 7 hours behind CET. Abbreviations are for reading: this page resolves CET to Europe/Berlin and CST to America/Chicago, which are the names that do not go ambiguous.

CET: Central European Time, anchored on Berlin. CST: US Central — China Standard Time also uses these letters.
