Please review the patch for test tools/jar/JarEntryTime.java

In which two issues fixed:

1. Test fails intermittently on checking the extracted files' 
last-modified-time are the current times.
    Instead of compare the file last-modified-time with pre-saved time 
value “now” (which is the time *before* current time, especially in a 
slow run, the time diff of “now” and current time is possible greater 
than 2 seconds precision (PRECISION)), test now compares the extracted 
file’s last-modified-time with newly created file last-modified-time.
2. Test may fail if run during the Daylight Saving Time change.
