One Year Difference using default template

Hello,

I've found an issue today with the date year on both telegram and mail notifications:

If i use the default Template:

$dateTool.format("YYYY-MM-dd HH:mm:ss", $event.serverTime, $locale, $timezone)

Result: 2020-12-29 05:06:48

If i change to use "long" Template:

$dateTool.long

December 29, 2019 at 5:10:52 AM CET

I check the time zone on database:

MariaDB [(none)]> SELECT @@global.time_zone;
+--------------------+
| @@global.time_zone |
+--------------------+
| SYSTEM             |
+--------------------+
1 row in set (0.001 sec)

MariaDB [(none)]> SELECT NOW();
+---------------------+
| NOW()               |
+---------------------+
| 2019-12-29 05:06:48 |
+---------------------+
1 row in set (0.002 sec)

And also, the system date is ok:
dom dic 29 05:08:01 CET 2019

How is possible to have the same date but with one year more?

Thanks for your help!!

Regards

Also, i put the system timedatectl result:

               Local time: dom 2019-12-29 05:31:58 CET
           Universal time: dom 2019-12-29 04:31:58 UTC
                 RTC time: n/a
                Time zone: Europe/Madrid (CET, +0100)
System clock synchronized: yes
              NTP service: active
          RTC in local TZ: no

Also, i have configured both attributes on user/Server with the web.

same problem. and yesterday everything was fine

I'm facing this problem too

Problem occurs due to this week being classified as week 1 of 2020. Using small ("yyyy") may solve the problem but I have not tested. Once someone has tested please post.

Yes!!! I've tested with small letters (yyyy) and it's ok!
