使用Javascript将unix时间戳转换为日期时间格式

Question

这是我第一次使用javascript编写Web应用程序。我目前正面临一个问题。我的应用程序，它应该在实时折线图中可视化（出现日期）和（出现频率）。问题是，我收到unix格式的时间戳数据。

我的问题。如何使用javascript将unix数据更改为数据时间格式？

这是json文件：

       [{"OccurrenceDate":"\/Date(1397602800000+0100)\/","OccurrenceFrequency":17},
       {"OccurrenceDate":"\/Date(1398207600000+0100)\/","OccurrenceFrequency":17},
       {"OccurrenceDate":"\/Date(1398639600000+0100)\/","OccurrenceFrequency":1},
       {"OccurrenceDate":"\/Date(1398726000000+0100)\/","OccurrenceFrequency":1},
       {"OccurrenceDate":"\/Date(1398898800000+0100)\/","OccurrenceFrequency":3},
