## 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.

## Constructor & Destructor Documentation

booster::ptime::ptime | ( | long long | seconds = `0`,
|  | int | nano = `0`
| ) |  |
| inline explicit

Create the POSIX time from seconds and nanoseconds.
