Why systemd-analyze from systemd service at multi-user.target does not output anything

.everyoneloves__top-leaderboard:empty,.everyoneloves__mid-leaderboard:empty,.everyoneloves__bot-mid-leaderboard:empty margin-bottom:0;

0

Having the following script:
boot-time-log.sh

#!/usr/bin/env bash

BOOT_TIME=$(systemd-analyze | cut --fields=10 --delimiter= )
echo -e "Boot time: $BOOT_TIMEn" > /var/log/boot_time.txt

And the following systemd service (enabled):
log_at_boot.service

[Unit]
Description=Log boot time 
User=root
Group=root

[Service]
ExecStart=/usr/bin/boot-time-log.sh

[Install]
Wants=network-online.target
After=network-online.target
Wants=multi-user.target
After=multi-user.target

When I restart the PC the contents of /var/log/boot_time.txt are:

Boot time: 

And if I run the script manually, then the contents are:

Boot time: 29.382s

How can I get the service execution to have the same output than the manual execution?

shell-script systemd

  I used a systemd timer for 15 seconds from "OnStartupSec", and works (There is proper output). If I use less seconds of delay, the output of systemd-analyze is empty. Does somebody know why the output of systemd-analyze is empty if executed too early? And if there is a cleaner way to get this result?

  I started down the path of while ! systemctl is-active "$(systemctl get-default)" but didn't get to the bottom of it, in case anyone wants to extend it from there.
