Detailed Description

This class represents POSIX time.

The time from Jan 1, 1970 in seconds in UTC (without leap seconds) similar to time_t.

ptime internally holds 64 bit integer for seconds part and int for nanoseconds part which gives fine-grained time representation.

booster::ptime::ptime	(	long long	seconds = 0,
		int	nano = 0
	)		[inline, explicit]

Create the POSIX time from seconds and nanoseconds.
