URL: https://github.com/apache/hudi/issues/8370

   I am reading at 
https://hudi.apache.org/docs/quick-start-guide#time-travel-query and 
https://hudi.apache.org/docs/quick-start-guide#point-in-time-query.
   
   
   Below are the two examples for the time travel query and point in time 
query. But it looks to me that these two queries are doing the same thing:  
they are both doing the `snapshot query` until the time:20210728141108100.
   
   Not sure I have understood correctly ,but I wonder why the query examples 
have two different names(time travel query vs point in time query).
   
   
   For the time travel query, the example in the doc is:
   
   ```
   spark.read.
     format("hudi").
     option("as.of.instant", "20210728141108100").
     load(basePath)
   
   ```
   
   For the point in time query, the example in the doc is:
   
   ````
   val beginTime = "000"  /// the begin time is 000,denoting the earlist commit
   val endTime = "20210728141108100"
   
   //incrementally query data
   val tripsPointInTimeDF = spark.read.format("hudi").
     option(QUERY_TYPE_OPT_KEY, QUERY_TYPE_INCREMENTAL_OPT_VAL).
     option(BEGIN_INSTANTTIME_OPT_KEY, beginTime).
     option(END_INSTANTTIME_OPT_KEY, endTime).
     load(basePath)
   tripsPointInTimeDF.createOrReplaceTempView("hudi_trips_point_in_time")
   spark.sql
   
   ````
