+/* Leap second stress test
+ * by: John Stultz (john.stultz(a)linaro.org)
+ * (C) Copyright IBM 2012
+ * (C) Copyright 2013, 2015 Linaro Limited
+ * Licensed under the GPLv2
+ *
+ * This test signals the kernel to insert a leap second
+ * every day at midnight GMT. This allows for stessing the
+ * kernel's leap-second behavior, as well as how 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 GMT.
+ * 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
+ * disruption.
+ *
+ * -i: Number of iterations to run (default: infinite)
+ *
+ * Other notes: Disabling NTP prior to running this is advised, as the two
+ * may conflict in thier commands to the kernel.
+ *
+ * To build:
+ * $ gcc leap-a-day.c -o leap-a-day -lrt
+ *
+ * This program is free software: you can redistribute it and/or modify
+ * it under the terms of the GNU General Public License as published by
