CONFIG_SYS_CLOCK_MAX_TIMEOUT_DAYS¶
Max timeout (in days) used in conversions
Type: int
Help¶
Value is used in the time conversion static inline function to determine
at compile time which algorithm to use. One algorithm is faster, takes
less code but may overflow if multiplication of source and target
frequency exceeds 64 bits. Second algorithm prevents that. Faster
algorithm is selected for conversion if maximum timeout represented in
source frequency domain multiplied by target frequency fits in 64 bits.
Default¶
365
