请使用

Please use UDF in Cosmos DB.

示例文档:

sample document:

udf:

udf:

function convertTime(unix_timestamp){

      var date = new Date(unix_timestamp*1000);
      var year = date.getFullYear();
      var month = ("0"+(date.getMonth()+1)).substr(-2);
      var day = ("0"+date.getDate()).substr(-2);
      var hour = ("0"+date.getHours()).substr(-2);
      var minutes = ("0"+date.getMinutes()).substr(-2);
      var seconds = ("0"+date.getSeconds()).substr(-2);

      return year+"-"+month+"-"+day+" "+hour+":"+minutes+":"+seconds;
}

SQL:SELECT udf.convertTime(c._ts) FROM c

当然，在这种情况下，您可以使用多种格式:转换用JavaScript计时的Unix时间戳

Surely , you could refer to varied format in this case: Convert a Unix timestamp to time in JavaScript

希望它对您有帮助.
