i agree. i also heard a requirement of this form expressed by the wot interest group in sapporo. We should either refer to the met ocean wg reference time, or build our own if that is not good enough.
This is not strictly owl-time, but it is very near by and entirely in-scope for us to take a position.
( chris, mentioning ISSUE-16 in the email gets the message against the issue in the tracker).

The Met Ocean Domain WG of OGC produced a Best Practice profile of the OGC WMS1.3 standard to capture some of these time concepts and improve interoperability arising from real world experience of interoperability problems. The BP gave a standard name for these non-standard time semantics ("Reference Time").
