date_time_zone

Section titled “date_time_zone”
struct date_time_zone (2 fields) source
§ int16_t utc_offset_min
§ int16_t dst_offset_min

date_time_expanded

Section titled “date_time_expanded”
struct date_time_expanded (7 fields) source

We use this one for processing

§ year_t year

§ uint8_t day_of_month

1 - 31

§ uint8_t day_of_week

0 - 6

§ uint8_t hour

§ uint8_t minute

0 - 59

§ uint8_t second

0 - 59

Type Aliases

Section titled “Type Aliases”

year_t

Section titled “year_t”
typedef uint16_t year_t
source

We’ll define these because this header + the implementations for various functions using struct date_time will need the annotations in types

day_t

Section titled “day_t”
typedef uint16_t day_t
source
