Summary

I have configured the docker variables to run every day at 02:00, but it runs at 21:27 and I don't know why. Sometimes, the first execution is done at the configured time. The last execution has scheduled the next one for 16:00.

Steps to reproduce

db-backup: restart: unless-stopped container_name: db-backup environment: TIMEZONE: Europe/Madrid TEMP_LOCATION: /backup/temp/ CONTAINER_ENABLE_MONITORING: FALSE DB_TYPE: mariadb DB_PORT: 3306 DEFAULT_BACKUP_LOCATION: FILESYSTEM DEFAULT_BACKUP_BEGIN: '0200' DEFAULT_BACKUP_INTERVAL: 1140 # backup every day DEFAULT_CLEANUP_TIME: 1140 # clean every day DEFAULT_CHECKSUM: SHA1 DEFAULT_COMPRESSION: GZ DB01_SPLIT_DB: FALSE volumes: - *** image: tiredofit/db-backup:latest

What is the expected correct behavior?

I would expect the backup to run at 02:00.
