Calculate Field in Mosaic dataset

[GualbertoHernández_Juárez]

Hi,

Create a mosaic dataset, extracted rasters from a netCDF file.

Add time to mosaic for use time slider, but are over written and applies it to last me all raster that form the mosaic, where each raster really should have its own time.

ie get the mosaic with time the raster last, for all raster mosaic. As long I can assign the time for each raster using calculate field?

thanks
