Could have one daily cron which executes a script. Within the script loop with a 60-second delay after each succesful job completion.
Within the loop within the script also test for a "stop" flag file and have another cron to set the "stop" flag file at the end of the day. Remember to delete the "stop" flag file just before exiting the script.

Btw. A cron running every minute will create at least 3x3,600=10,800 entries in the cron log per day. If the cron job produces any untrapped output it will also create 3,600 emails per day.

NAME
crontab - maintain crontab files for individual users (V3) SYNOPSIS
crontab [ -u user ] file crontab [ -u user ] { -l | -r | -e } DESCRIPTION
Crontab is the program used to install, deinstall or list the tables used to drive the cron(8) daemon in Vixie Cron. Each user can have their own crontab, and though these are files in /var, they are not intended to be edited directly. If the allow file exists, then you must be listed therein in order to be allowed to use this command. If the allow file does not exist but the deny file does exist, then you must not be listed in the deny file in order to use this command. If neither of these files exists, then depending on site-dependent configuration parameters, only the super user will be allowed to use this command, or all users will be able to use this command. If the -u option is given, it specifies the name of the user whose crontab is to be tweaked. If this option is not given, crontab examines "your" crontab, i.e., the crontab of the person executing the command. Note that su(8) can confuse crontab and that if you are running inside of su(8) you should always use the -u option for safety's sake. The first form of this command is used to install a new crontab from some named file or standard input if the pseudo-filename ``-'' is given. The -l option causes the current crontab to be displayed on standard output. The -r option causes the current crontab to be removed. The -e option is used to edit the current crontab using the editor specified by the VISUAL or EDITOR environment variables. After you exit from the editor, the modified crontab will be installed automatically. SEE ALSO
crontab(5), cron(8) FILES
/etc/cron.allow /etc/cron.deny STANDARDS
The crontab command conforms to IEEE Std1003.2-1992 (``POSIX''). This new command syntax differs from previous versions of Vixie Cron, as well as from the classic SVR3 syntax. DIAGNOSTICS
A fairly informative usage message appears if you run it with a bad command line. AUTHOR
