First, you have an extra dollar sign (shown in red above) that shouldn't be there.

Well you could us the ? operator like this:

argument=length($1) ? $1 : "default if empty"

Condition ? one and only one true expr : one and only one false expr
you must have false expr also:

It is unclear why you want to convert your local time to the time in Ireland. If what you really want is to display the current time in Ireland, the proper command would be:

TZ="Europe/Dublin" date

It gets the value of the variable "expand" and treats this as a variable name and the fetches its value.

So
$ t=5
$ x=t
$ y=x
$ echo ${!x}
5
$ echo ${!y}
t

I'd suggest not using eval at all, just code your own allowed expansions e.g.:

expand='$RANDOM'
[ ${expand:0:1} = "$" ] && {
expand=${expand:1}
expand=${!expand}
}

It's not whether it "likes" it or not. It's because of the order shell processes a statement.

The temporary IFS assignment only becomes valid when the statement is executed -- but in order to...

It has to, to avoid deadlocks. Which runs first, the echo or the read? Will either of them hang, waiting for the other? Make them independent and it doesn't matter.
