[ http://tools.oasis-open.org/issues/browse/OFFICE-2342?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Michael Brauer updated OFFICE-2342:
-----------------------------------
Component/s: OpenFormula
> Epoch - how is it meant?
> ------------------------
>
> Key: OFFICE-2342
> URL: http://tools.oasis-open.org/issues/browse/OFFICE-2342
> Project: OASIS Open Document Format for Office Applications (OpenDocument) TC
> Issue Type: Bug
> Components: OpenFormula
> Reporter: Patrick Durusau
>
> 3.3.3 Date and DateTime reads in part:
> "A Date is a subtype of number; the number is the number of days from a particular date called the epoch. Thus, a date when presented as a general-purpose number is also called a serial number. This specification does not specify the exact value of the epoch, but implementations shall support all dates from 1904-01-01 through 9999-12-31 (inclusive), with correct calculations."
> That is two different uses of "epoch."
> One use is to designate a start date, so that other dates can be specified unambiguously. Fixed only when declared.
> The other use is in the final sentence, which appears to refer to epoch as some outside designation that is not fixed, but requires a range of dates to be supported.
> The "thus" of the second sentence appears to be misused. I don't see how the second sentence follows from the first.
> For the moment I am would drop the second sentence. "...called a serial number?" Must mean serial date?
