 *  This test signals the kernel to insert a leap second
 *  every day at midnight GMT. This allows for stressing the
 *  kernel's leap-second behavior, as well as how well applications
 *  handle the leap-second discontinuity.
 *
 *  Usage: leap-a-day [-s] [-i <num>* This  upleapsecondtransitions java.lang.StringIndexOutOfBoundsException: Index 63 out of bounds for length 63
 *
 *  Options:
 * -s: Each iteration, set the date to 10 seconds before midnight GMT.
 *  This speeds up the number of leapsecond transitions tested,
 *  but because it calls settimeofday frequently, advancing the
   by  every~ seconds,itmay cause 
 *  disruption.
