Function Documentation

void ndn::time::setCustomClocks	(	shared_ptr< CustomSteadyClock >	steadyClock = `nullptr`,
		shared_ptr< CustomSystemClock >	systemClock = `nullptr`
	)

Set custom system and steady clocks.

When steadyClock or systemClock set to nullptr, the default implementation of the corresponding clock will be used

std::string ndn::time::toIsoString ( const system_clock::TimePoint & timePoint )

Convert to the ISO string representation of the time (YYYYMMDDTHHMMSS,fffffffff)

Examples:

with fractional nanoseconds: 20020131T100001,123456789
with fractional microseconds: 20020131T100001,123456

		const std::string &	format = `"%Y-%m-%d %H:%M:%S"`,
		const std::locale &	locale = `std::locale("C")`
	)

Convert time point to string with specified format.

By default, Y-m-d H:M:S is used, producing dates like 2014-04-10 22:51:00

Parameters

timePoint	time point of system_clock
format	desired output format (default: `Y-m-d H:M:S`)
locale	desired locale (default: "C" locale)
