Typedefs
using	itch::ItchTimePoint = std::chrono::sys_time< std::chrono::nanoseconds >
	A system-clock time point at nanosecond resolution.

Functions
constexpr auto	itch::to_time_point (std::chrono::year_month_day session_date, std::uint64_t nanos_past_midnight) noexcept -> ItchTimePoint
	Combines a session date with an ITCH timestamp into a time point.
auto	itch::format_timestamp (std::uint64_t nanos_past_midnight) -> std::string
	Formats a raw ITCH timestamp as a time-of-day string.
auto	itch::format_time_point (std::chrono::year_month_day session_date, std::uint64_t nanos_past_midnight) -> std::string
	Formats a session date plus an ITCH timestamp as a full date-time.

Detailed Description

Helpers for converting raw ITCH nanoseconds-past-midnight timestamps into absolute time points and human-readable strings.

ITCH timestamps carry no date or time-zone of their own, so every conversion here takes the session date as an explicit parameter and performs no time-zone adjustment.
