I have seen a module proposal on the [EMAIL PROTECTED] mailing list: Time::Seconds::GroupedBy. See
http://www.xray.mpe.mpg.de/mailing-lists/modules/2004-07/msg00209.html I have invited the author to discuss it on our mailing-list. Anyhow, when reading his code, there is a good idea for DateTime::Duration: in addition to the "year" unit, which varies from 365 days to 366, DT::Duration could feature other units such as tropic_year, sideral_year or whatever, with a fixed length of 31556931 seconds. On the other hand, maybe it exists in some Astro:: module I have not yet read...
