Real-Time Clock Implementation on Exynos 4412
RTC Fundamentals
Real-Time Clock (RTC) is an integrated circuit designed to maintain accurate timekeeping in embedded systems. It provides reliable system time including hours, minutes, seconds, date, month, and year information. The RTC continues operating during system power-off states through backup battery power, requiring minimal external ...

Time Fundamentals
Unix Timestamps
A Unix timestamp is the total number of seconds elapsed since 00:00:00 UTC on January 1, 1970, ignoring leap seconds. It is stored as a 32-bit or 64-bit integer. All time zones use the same timestamp value, with local time calculated by adding a timezone offset.
UTC/GMT
GMT (Greenwich Mean Time) is a timekeepin ...
