I am trying to export an image to Assets after adding a band representing time using the following code:

//Function to add a timestamp as a new band//
var createTimeBand = function(image) {
  return image.addBands(image.metadata('system:time_start').divide(3.154e10));
};

var img = ee.Image('LANDSAT/LC08/C01/T1_TOA/LC08_062011_20130719');
var img = createTimeBand(img);

Export.image.toAsset({
  image: img,
  scale: 30
});

but I am getting this error after a few seconds when I try and run the task:

enter image description here

There seem to be no problems exporting without the timestamp band, but it is not clear to me why the timestamp causes this error.

Unlike property names, band names cannot contain the colon character. Try renaming the band you are adding:

.metadata('system:time_start').rename('system_time_start')
