Also, EPOCHREALTIME may not have "." as the decimal delimiter since it
uses the one of the current locale (LC_NUMERIC). So it's more
appropriate to use [!0-9] rather than ".".

        now=$EPOCHREALTIME
        printf -v second '%(%S)T.%s' "${now%[!0-9]*}" "${now#*[!0-9]}"
        printf -v minute '%(%M)T' "${now%[!0-9]*}"
        printf -v hour '%(%H)T' "${now%[!0-9]*}"
