[Mapserver-users] time support

[nicolas.fortin at ec.gc.ca]

I'm really interested in future development of this functionnality cause we
have 100 years of diverse Performance Indicator (PI) order by QTID (Time
Quarter = 1/48 year) where QTID 1 = 1/1/1900 

With this, I could add a time parameter in my PI layers and I'll have 100
years of data for each of those layers.
Only one layer instead of 100!
It would be so great and time-saving!

You can do time-based queries with ranges and intervals from a single layer.
Is this what you mean?
