Here is a cron entry that would probably work:
However, there are some gotchas:
1. You may not have permission to run cron jobs, so cron.allow would need your account name adding. (And easy way to check is to issue the command "crontab -e" and see if it errors or works.)
2. Your script may not work depending upon the scripting language you've used and OS you're running on (ie. Solaris comes with only Bourne shell support in cron).
3. Your script may assume environment variables that work when you run it interactively, but aren't there when it's run via cron.
4. Your OS (bloomin' Solaris again!) may be configured to only allow a limited number of concurrent cron jobs, so other schedules may impact yours.
Have fun!

cron
cron(8) System Manager's Manual cron(8)NAME
cron - The system clock daemon
SYNOPSIS
/usr/sbin/cron
DESCRIPTION
The cron daemon runs shell commands at specified dates and times. Commands that are to run according to a regular or periodic schedule are
found within the crontab files. Commands that are to run once only are found within the at files. You submit crontab and at file entries
by using the crontab and at commands. Because the cron process exits only when killed or when the system stops, only one cron daemon
should exist on the system at any given time. Normally, you start the cron daemon from within a run command file.
During process initialization and when cron detects a change, it examines the crontab and at files. This strategy reduces the overhead of
checking for new or changed files at regularly scheduled intervals. The cron command creates a log of its activities. The cron daemon
must be started from the system startup scripts because it must begin execution without a login user ID set. The cron daemon starts each
job with the following process attributes stored with the job by the invoking process: Login user ID Effective and real user IDs Effective
and real group IDs Supplementary groups
It also establishes the following attributes from the authentication profile of the account associated with the login user ID of the invok-
ing process: Audit control and disposition masks Kernel authorizations
DIAGNOSTICS
The at and batch programs will refuse to accept jobs submitted from processes whose login user ID is different from the real user ID.
FILES
Specifies the command path. Main cron directory Directory containing the crontab files. List of allowed users. List of denied users His-
