   Thanks @chenjunjiedada, I was able to reproduce. 
   
   I've been looking into this and I think 
https://github.com/apache/iceberg/commit/bca6380c56469c01f4eb02cb91f905dd57ad03d3
 seems to fix both test cases as they are. 
   
   However, I added a test case 
https://github.com/apache/iceberg/commit/e61cc6187c6a13b7913f66f548f4be9d05d2a717
 for multiple timezones on `TestLocalScan testFilterWithDateAndTimestamp` and 
there seems to be something wrong going on: 
   1. Test runs fine for `America/Los_Angeles` passes
   2. Test runs fine for `Europe/London` fails
   
   ```
   org.apache.iceberg.data.TestLocalScan > testFilterWithDateAndTimestamp[1] 
FAILED
       java.lang.AssertionError: TZ: Europe/London
           at org.junit.Assert.fail(Assert.java:88)
           at org.junit.Assert.assertTrue(Assert.java:41)
           at 
org.apache.iceberg.data.TestLocalScan.testFilterWithDateAndTimestamp(TestLocalScan.java:498)
   ```
   Values:
   ```
   -- 1. America/Los_Angeles run
   Date min: -136246
   Date max: 134321
   -- 2. Europe/London run (fail)
   Date min: -136246
   Date max: 134321
   Record(1986-01-30T08:11:32.189299Z, 1995-05-15T23:02:42.319212, 1596-12-21, 
00:29:18.577901)
   ```
   
   If I switch the order of the tests, the second TZ test keeps failing 
(different timezone as the failed test before):
   
   ```
