If a WMS has a time extent of:
2001-10-30/2004-10-30
..of, let's say, daily observations, and my time request is:
2000-10-30/2002-10-30
...is this extent out of range?
response from wms-dev :
If the available dates are declared as 2001-10-30/2004-10-30/P1D and the
request is for 2000-10-30/2002-10-30/P1D, then I recommend the following:
(a) IF attribute 'nearestValue' is missing or has the value 0, then issue an
InvalidDimensionValue exception.
(b) ELSE return content for 2001-10-30/2002-10-30/P1D and include the HTTP
response header "Warning: 99 Nearest value used: TIME=2001-10-30/2002-10-
30/P1D".
See WMS 1.1.1 Annexes C.3 & C.5.2 or WMS 1.3/ISO DIS 19128 Annexes C.2 & C.4.3.
(Note error in WMS 1.1.1, p.59 where the plural "nearestValues" is used in the
text.)

Currently the Nearest Value is not used.
