Understanding SysTick Timer Frequency Calculations for Software Delays on STM32
Analyzing the Core Mechanism Behind SysTick Based Delays
Developers frequently encounter pre-written delay functions such as Delay() in reference projects, yet the mathematical foundation required to generate these routines oftan remains obscure. While widely utilized, understanding the relationship between the system clock frequency and the ti ...

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 ...
