logger_default_days_in_year()

static int32_t logger_default_days_in_year ( int32_t  year )

static

Parameters

[in]

year

Gregorian calendar year.

Returns

366 if year is leap, otherwise 365.

Definition at line 49 of file logger_default_utc_timestamp.c.

logger_default_epoch_time_to_date()

bool logger_default_epoch_time_to_date	(	logger_default_utc_timestamp_t *	out,
		const osal_time_t *	time
	)

This helper interprets time->epoch_seconds as a UTC+0 Unix epoch-time value and converts it into calendar and clock fields stored in *out.

Parameters

[out]	out	Receives the converted UTC timestamp. Must not be NULL.
[in]	time	Epoch-time value to convert. Must not be NULL.

Return values

true	Conversion succeeded and *out was populated.
false	One or more arguments are invalid.

A year is leap if it is divisible by 4, except century years that are not divisible by 400.

Parameters

[in]

year

Gregorian calendar year.

Return values

true	year is a leap year.
false	year is not a leap year.
