[mapserver-users] TIme support on mapserver 5.6.3, it's working?

[Alexander Petkov]

I suggest that you carefully inspect your definitions in your mapfile,
as well as the data in the Postgis DB itself.
Turn debugging on, and inspect the log file closely.
Also, if you already haven't, enable PostgreSQL logging, inspect
incoming requests to your database as well.

For example, one inconsistency that is evident from your map file is
the date format--the "wms_timeextent" item for the "sat_w" layer
contains a date range, while your Postgis data also has a timestamp
data type with HH24:MI data. I would eliminate those inconsistensies
first.

List each time step individually (comma separated) in your mapfile ,
since your number of records for the time being is small, rather than
specifying a date range.

Again, do not be shy about inspecting the log files. Randomly trying
"a lot of combinations", as well as different Mapserver versions
hoping that something will work will likely not help.
