tme_point

Represents a point in time storing a TDuration indicating the time

interval from the start of the TClock's epoch.

Assignment

ETL_CONSTEXPR14

time_point& operator =(const time_point& rhs)

ETL_NOEXCEPT

Assignment operator.

____________________________________________________________________________________________________

Access

ETL_NODISCARD

ETL_CONSTEXPR14 duration time_since_epoch() const

ETL_NOEXCEPT

Returns a duration representing the amount of time between this and the clock's epoch.

____________________________________________________________________________________________________

Member arithmetic operators

ETL_CONSTEXPR14 time_point& operator +=(const duration& rhs)

ETL_NOEXCEPT

Adds a duration.

______________________________________________

ETL_CONSTEXPR14 time_point& operator -=(const duration& rhs)

ETL_NOEXCEPT

Subtracts a duration.

____________________________________________________________________________________________________

Constants

ETL_NODISCARD

static ETL_CONSTEXPR14 time_point min()

ETL_NOEXCEPT

Returns a time_point with the smallest possible duration.

______________________________________________

ETL_NODISCARD

static ETL_CONSTEXPR14 time_point max()

ETL_NOEXCEPT

Returns a time_point with the largest possible duration.

____________________________________________________________________________________________________

Rounding

template <typename TToDuration, typename TClock, typename TDuration>

ETL_NODISCARD

ETL_CONSTEXPR14

etl::chrono::time_point<TClock, TToDuration>

floor(const etl::chrono::time_point<TClock, TDuration>& tp)

ETL_NOEXCEPT

Rounds down a duration to the nearest lower precision.

______________________________________________

template <typename TToDuration, typename TClock, typename TDuration>

ETL_NODISCARD

ETL_CONSTEXPR14

etl::chrono::time_point<TClock, TToDuration>

ceil(const etl::chrono::time_point<TClock, TDuration>& tp)

ETL_NOEXCEPT

Rounds up a duration to the nearest higher precision.

______________________________________________

template <typename TToDuration, typename TClock, typename TDuration>

ETL_NODISCARD

ETL_CONSTEXPR14

etl::chrono::time_point<TClock, TToDuration>

round(const etl::chrono::time_point<TClock, TDuration>& tp)

Compare day with another.

If time_point < other, returns -1

else if time_point > other, returns 1

else returns 0
