template <typename TClock, typename TDuration = typename TClock::duration>
class time_point;
Represents a point in time storing a TDuration indicating the time
interval from the start of the TClock's epoch.
Member types
using clock = TClock
using duration = TDuration
using rep = typename TDuration::rep
using period = typename TDuration::period
Constructors
ETL_CONSTEXPR

ETL_NOEXCEPT
Description
Assignment operator.
Access
ETL_NODISCARD
ETL_CONSTEXPR14 duration time_since_epoch() const
ETL_NOEXCEPT
Return
A duration representing the amount of time between this and the clock's epoch.

static ETL_CONSTEXPR14 time_point max()
ETL_NOEXCEPT
Return
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
Description
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
Description
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)

else if time_point > other, returns 1
else returns 0
