The last.fm scrobble feature on Airsonic has been broken for me since recently. I have the TZ environment variable configured as per documentation. I get the following in my logs while trying to scrobble:

The timezone and time is correctly set both within the container and on the host:
date && docker exec airsonic date
Wed Apr 10 03:29:19 IST 2019
Wed Apr 10 03:29:20 IST 2019
My entire configuration is available at https://github.com/captn3m0/nebula/blob/master/media/airsonic.tf if it helps.
