+: [Partitions]("https://aicloud-docs.claaudia.aau.dk/slurm/#selecting-a-partition") may impose time limits. These limits define the longest time your job can run for in the specific partition. They can be viewed with the `sinfo` command.
+If your job has not ended by this time limit, it will be automatically cancelled.
+In the days leading up to the [service windows]("https://www.researcher.aau.dk/guides/research-data/high-performance-computing/terms-and-conditions-of-use-of-hpc-resources#scheduled-service-windows-for-strato-and-ai-cloud"),
+you will also be met by a time limit, which prevents you from launching jobs with end dates that surpass the date of the servicewindow. 
+If the `time` parameter is not set, Slurm assumes you ask for the default maximum time for the partition. To submit a job that runs for 1 day and 8 hours, you can simply add `time=1-8:00:00` to your Slurm command.
+Make sure to read about our recommendations for using [checkpointing]("https://aicloud-docs.claaudia.aau.dk/slurm/#checkpointing) to work with time limits.
