Warp the Timestamps or something.
This library is for use with the suggested Erlang VM args for time warp mode and time correction:
$ cat config/vm.args
These settings require that you have only [Time Warp Safe Code](http://erlang.org/doc/apps/erts/time_correction.html#Time_Warp_Safe_Code).
Time correction is enabled by Erlang by default if it supported by your system, while the default time warp mode is `no_time_warp` because this is how the runtime behaved before the addition of time warp modes.
Example usage to find the time elapsed while performing some function and converting to a timestamp that is in microseconds since the epoch, so has meaning outside of the Erlang runtime. The `wts` timestamp uses the Erlang runtime's `native` time unit for the best accuracy and precision and only converts to microseconds when returning the result of `duration/2` and `to_absolute/1`.
> StartTime = wts:timestamp().
> %% do something
> EndTime = wts:timestamp().
%% get the duration in microseconds
> wts:duration(StartTime, EndTime).
%% convert to microseconds since the epoch
Additionally there is support for converting to an rfc3339 format string:
