to trigger/signal a rebuild for the transition 5.8.8 -> 5.10.0.
The list of packages is computed by finding all packages which end
up having either of PERL5_USE_PACKLIST, BUILDLINK_API_DEPENDS.perl,
or PERL5_PACKLIST defined in their make setup (tested via
"make show-vars VARNAMES=...").
A Time::Clock object is a twenty-four hour clock with nanosecond
precision and wrap-around. It is a clock only; it has absolutely
no concept of dates. Vagaries of date/time such as leap seconds
and daylight savings time are unsupported.
When a Time::Clock object hits 23:59:59.999999999 and at least one
more nanosecond is added, it will wrap around to 00:00:00.000000000.
This works in reverse when time is subtracted.
Time::Clock objects automatically stringify to a user-definable
format.
