# 用語(terms)
|term| Description|
|:--|:--|
|DST| Daylight Saving Time, also know as Day Light Saving (abbreviated DLS), is the practice of advancing clocks during summer months so that evening daylight lasts longer, while sacrificing normal sunrise times. Typically, regions that use daylight saving time adjust clocks forward one hour close to the start of spring and adjust them backward in the autumn to standard time.

master-slaveという用語は、SAEのLINの規定をはじめ、順次言い換えが進んでいる。
coreの場合はbootまたはprimaryとsecondaryという用語で記載している。
自分の資料では、LINではcontroller, peripheralという用語で記載している。
ISO規格が改定があれば、AUTOSAR文書も改定することが想定できる。
