+/* Time bounds setting test
+ * by: john stultz (johnstul@us.ibm.com)
+ * (C) Copyright IBM 2012
+ * Licensed under the GPLv2
+ *
+ * NOTE: This is a meta-test which sets the time to edge cases then
+ * uses other tests to detect problems. Thus this test requires that
+ * the inconsistency-check and nanosleep tests be present in the same
+ * directory it is run from.
+ *
+ * To build:
+ * $ gcc set-2038.c -o set-2038 -lrt
+ *
