// Tests FormatEpochTimeInMillisAsIso8601(). The correctness of conversion
// for particular dates below was verified in Python using
-// datetime.datetime.fromutctimestamp(<timetamp>/1000).
+// datetime.datetime.fromutctimestamp(<timestamp>/1000).
// FormatEpochTimeInMillisAsIso8601 depends on the current timezone, so we
