In many ways, daemon is similar to background process without controlling terminal. However, there are more implications for a daemon: almost idle if no request to work on, listen to (actually, waken by via sth else) a request coming from either a TCP/UDP port, or a signal, multithread or multiprocess based application.
So simply saying making a script a daemon may not make sense in many scenarios. Due to the nature of daemon, people rarely uses script to write a daemon application.
Hope it clarifies,
Tom

timedsetup
timedsetup(8) System Manager's Manual timedsetup(8)
NAME
timedsetup - Performs initial setup of the time server daemon (timed).
SYNOPSIS
/usr/sbin/timedsetup
DESCRIPTION
The timedsetup command is an interactive script that can be used to perform initial time service configuration for your system.
By default, timed does not start at boot time. The timedsetup script asks if you want the timed daemon to be started at boot time, and
prompts you for any options to pass to the timed daemon whenever it is invoked. The script then starts the timed daemon.
For more information on the timed options, see the timed(8) reference page.
Note
The timed daemon is provided for compatibility. Tru64 UNIX also provides support for the Network Time Protocol (NTP) through the xntpd
daemon. Compaq recommends you use NTP for time synchronization. If your system is configured to run NTP, the timedsetup command passes
the -E and -M options to the timed daemon by default.
If you plan to run both the timed daemon and NTP, you should configure NTP first.
RESTRICTIONS
In configurations with two or more hosts each connected to the same two or more subnetworks, only one of the host can run the timed with
the -M option.
FILES
Specifies the command pathname The timed startup and shutdown script Specifies timed parameters pertinent to a specific system
