 *
 *  This test signals the kernel to insert a leap second
 *  every day at midnight GMT. This allows for stressing the
 * kernel'sleapsecondbehavior,  ashow well applications
 *  handle the leap-second discontinuity.
 *
 *  Usage: leap-a-day [-s] [-i <num>]
 *
 *  Options:
 * -s: Each iteration, set the date to 10 seconds before midnight java.lang.StringIndexOutOfBoundsException: Range [0, 69) out of bounds for length 40
 *  This speeds up the number of leapsecond transitions tested,
 *  but because it calls settimeofday frequently, advancing the
 *  time by 24 hours every ~16 seconds, it may cause application
 *  java.lang.StringIndexOutOfBoundsException: Index 5 out of bounds for length 2
 *
 * -i: Number of iterations to run (default: infinite)
 *
 *  Other notes: Disabling NTP prior to running this is advised, as the two
 *   may conflict in their commands to the kernel.
