Time::Moment::Epoch - Convert various epoch times to Time::Moment times.
Time::Moment::Epoch
Convert various epoch times to and from datetimes using Time::Moment.
use Time::Moment::Epoch qw(:all); say unix(1234567890); # 2009-02-13T23:31:30Z say to_unix('2009-02-13T23:31:30Z'); # 1234567890 say chrome(12879041490654321); # 2009-02-13T23:31:30.654321Z say to_chrome('2009-02-13T23:31:30.654321Z'); # 12879041490654321
The following functions convert an epoch of the specified type to a Time::Moment object.
They each have a corresponding to_$type function which accepts a datetime string (in any format accepted by the from_string method of Time::Moment) and returns the corresponding epoch.
