question: public void checkToken ( String token ) { if ( token != null && ! token . isEmpty ( ) && ( System . currentTimeMillis ( ) - tokenLastChecked ) / 1000 > TOKEN_CHECK_DELAY ) { LOGGER . info ( "Checking token.." ) ; tokenLastChecked = Long . valueOf ( System . currentTimeMillis ( ) ) ; verifyToken ( token ) ; } }
target:  Verifies token, but only once the delay has passed. For automatic checks instead of manual ones.
