Fix abnormal evalMetrics performances


If you are experiencing bad performances with evalMetrics it might come from the timeZone field you specify on the EvalMetricsSpec.

If you have access to detailed logs, check for Timeseries.fromObjStream under your evalMetrics action. It means that the Metric Engine had to cast all the data points timestamps to a different timeZone.

To solve this, you can simply set the EvalMetricsSpec timeZone field to ‘None’.
