get_epochrealtime() casts tv.tv_sec (a time_t a.k.a. int) to unsigned
int causing EPOCHREALTIME to not behave correctly before the Unix Epoch.
The definition is seconds since the Unix epoch.
why disregard or invalid, mark 0 is that date, less is minus, .. all working

Except you're wrong.
$ val=foo
$ declare "$val"='x'
$ declare -p "$val"
declare -- foo="x"
$ val=bar
$ declare -a "$val"='(baz quux)'
$ declare -p "$val"
declare -a bar=([0]
yea i dunno to say, i dont care, peace..

It would be nice to have a parameter transformation (e.g. "${par@p}")
that expands $par to a string that will not be expanded by PS1, PS2, &c.
example:
tmp_var=$(blabla) # this variable will not exist when PS1 is expanded
PS1="blabla ${tmp_var@p} blabla"
I think a valid way to achieve the sa

It's not that simple. Calendars get really *interesting* if you go
farther back in history. The switch from the Julian to the Gregorian
calendar di
That is not at all the same thing.
$ t='~' q='?' s='*' n=$'\n' bn='\n'
$ a="hello ${t@Q} ${q@Q} ${s@Q} ${n@Q} ${bn@Q} hi"
$ printf '%s\n' "${a@P}"
hello '~' '?' '*' $'
' '
' hi
With the parameter transformation I requested, this is what should be printed:
$ t='~' q='?' s='*' n=$'\n

even if you remove the first and last ':
1) that is 3 PEs as the solution i described (${a//\\/}
${a//\`/\\\`} ${a//$/\\$} vs ${a@Q} ${a#\'} ${a%\'} )
2) it doesn't actually accomplish anything:
~ --${@Q}-> '~' --${#\'

Sorry, that was a bad example. Still, it does not accomplish anything:
\w --${@Q}-> '\w' --${#\'}-> \w' --${%\'}-> \w

In this case, the data may be organized by pairs.

It seems to me that you can just put '$par' (not "$par") in PS1.
Then, the suggested "${par@p}" can be simply '$par
