   This may be a timezone issue. `TZ=UTC mvn clean install` will fix this.
   
   It seems that `45935000` is `1970-01-01T12:45:35Z` in UNIX time (unit is 
milliseconds not seconds).

   ```console
   $ ruby -r time -e 'p Time.parse("1970-01-01T12:45:35Z").to_i * 1000'
   45935000
   ```
   
   +05:30 UNIX time is `65735000`:
   
   ```console
   $ ruby -r time -e 'p (Time.parse("1970-01-01T12:45:35Z").to_i + (5.5 * 60 * 
60)) * 1000'
   65735000.0
   ```
