all: Refactoring work with time using boost::chrono
Now the library has two clocks: time::steady_clock and
time::system_clock, following (boost|std)::chrono. In addition to
standard now() method, the library contains several helpers to convert
to/from UnixTimestamp (microsecond resolution) and IsoString (optional
microsecond resolution). The IsoString conversions use
boost::posix_time routines, since boost::chrono supports extended IO
support only starting boost version 1.52 (Boost Chrono V2).
This commit breaks compatibility with previous API. All time-related
Data/Interest calls must explicitly use time units to specify
FreshnessPeriod/InterestLifetime.
Brief usage/conversion guide:
- creation of time units does not support double/float types. If
necessary to create time unit from double, ``ndn::duration<double>`` (for
seconds) needs to be used instead. In some cases, this would also
require ``ndn::duration_cast``, if the target is not ``ndn::nanoseconds``.
- ndn::getNow, ndn::ndn_getNowMilliseconds, ndn::time::now are all
removed in favor of the now() method in a specific clock:
* time::system_clock::now();
* time::steady_clock::now();
- When necessary to convert system_clock::TimePoint to unix timestamp,
``time::toUnixTimestamp`` can be used. This method return number of
milliseconds since UNIX epoch as ``ndn::time::milliseconds`` type.
Use count() method to obtain number as an integral value.
