Probably, you'd do it through an annotation layer. What version are you using?
What interface (CGI, WMS, WCS)? Basically the idea would be to funnel the time
parameter into a TEXT expression in the annotation layer. Layer would look like
(assuming a variable called 'time' is passed) this I think:
LAYER
NAME 'timestamp'
TYPE ANNOTATION
STATUS DEFAULT
TRANSFORM LL # lower-left corner of the
FEATURE
POINTS 10 10 END
END
VALIDATION
'time' 'some expression that matches time values'
END
CLASS
LABEL
...
END
TEXT '%time%'
END
END
This would plop the passed time in the lower left corner of the output, or at
least I think it should.

Subject: [mapserver-users] how to add a time stamp on raster data
Hi all,
We have a set of time-series data. Is it popossible to add a time stamp, i.e.
the value of time parameter in the request, on raster data? Thanks.
