Please confirm that you are talking about ETA and not ETE. The ETA is not a defaulted instrument, so you would have had to add this one.
The ETA would not change much unless the closure rate changed, it could appear to be stuck. Try turning 45 degrees and seeing if the ETA increases. ETA is the Estimated Clock Time of Arrival, ETE is the Estimated Time Enroute. If it is shows 00:14 for the ETA, that is 12:14 after midnight. You might look at your Time Zone. The ETE would continue to count down as you approach your point.
