i cant see whats the issue, .. ps1 + propt command + date

[Alex fxmbsw7 Ratchev]

i got prompt changing code, in which i wished to also display a ( non
updating date )

i wrote the following code in $PROMPT_COMMAND
but the second element of prptnow2 ( by epochrealtime dot subsecond )
doesnt seem to exist any
the final $prptnow3 string is correctly formatted but the +=.<here> doesnt
append anything

also in term i tried declare -p prptnow2 and funkily it tells me it doesnt
exist
.. does anyone see anything obvious i miss here .. ?

prptnow=$EPOCHREALTIME saveIFS IFS=. prptnow2=( $prptnow ) restoreIFS \
dfslist=$( prptrecents )

printf -v prptnow3 '%(%F , %T)T' $prptnow2
prptnow3+=.${prptnow2[1]}
