> Issue Type: Task
> Reporter: Elizabeth Yam
> Assignee: Elizabeth Yam
> Priority: Major

> Some datasets don't have a time variable and have a timestamp in their
> metadata and file headers instead. Without a convention, we need to be able
> to pull the timestamp, given the variable name and add it to the nexus tile.
