libtime-duration-perl binary package in openKylin Yangtze V1.0 amd64

 Time::Duration provides functions for expressing time spans in rounded
 or exact terms. So while
 .
    say duration_exact(86399);
 .
 will correctly give "23 hours, 59 minutes, and 59 seconds",
 .
    say ago(86399);
 .
 will output the rounded time span as "1 day ago".
 .
 The provided functions are duration(), ago(), from_now(), later() and
 earlier(), along with their *_exact counterparts. The precision used
 for rounding can be specified, and version 1.10 added a millisecond
 mode.
