I can't imagine a company setting a policy against using one of the most powerful friends a sysadmin has. Amazing what people do.... But, I've an open mind. Convince me that prohibiting the use of cron is a good idea.

sleep
sleep(3) Library Functions Manual sleep(3)NAME
sleep - Suspends execution for an interval of time
LIBRARY
Standard C Library (libc.a) Threads Library (libpthreads.a)
SYNOPSIS
#include <unistd.h>
unsigned int sleep ( unsigned int seconds );
STANDARDS
Interfaces documented on this reference page conform to industry standards as follows:
sleep(): XPG4, XPG4-UNIX
Refer to the standards(5) reference page for more information about industry standards and associated tags.
PARAMETERS
Specifies the number of seconds to sleep.
DESCRIPTION
The sleep() function suspends execution of a process for the interval specified by the seconds parameter. The suspension time may be
longer than requested due to the scheduling of other activity by the system.
In a multi-threaded environment, the sleep() function is redefined so that only the calling thread is suspended.
RETURN VALUES
If the sleep() function returns because the requested time has elapsed, it returns 0 (zero). If the sleep() function returns because it
caught a signal, the function returns the number of seconds remaining in the suspension.
