Steve,

Thank you for your answer. I have tried the method you suggest. But it prints out "%time%, not the value of time.

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.

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.
