In #786, we added support for improving the performance of encoding time by allowing encoder implementations to implement AppendTimeLayout. If the encoder implements, `AppendTimeLayout(time.Time, string)`, some of the time encoders shipped with Zap will use that method, which in turn can make use of `Buffer.AppendTime`. That change inadvertently broke the JSON output for arrays of time that make use of that functionality. Compare the old version of AppendTimeLayout with AppendString (both operations append a string to the array). func (enc *jsonEncoder) AppendString(val string) { enc.addElementSeparator() enc.buf.AppendByte('"') // ... } func (enc *jsonEncoder) AppendTimeLayout(time time.Time, layout string) { enc.buf.AppendByte('"') // ... } Without the `enc.addElementSeparator` call, `AppendTimeLayout` does not include the `,` separator between array elements, instead yielding the following. ["2001-12-19T00:00:00Z""2002-12-18T00:00:00Z""2003-12-17T00:00:00Z"] Fixes #798
