In my frontmatter, I have added two fields, start_at and stop_at
start_at: 08:00:00
stop_at: 12:00:00
In my template I would like to show the duration between stop_at and start_at
I tried with {{ time .Params.stop_at "15:04:05" }} because I wanted to convert the string to a time but the parser does not recognize the pattern (12:00:00 unable to parse date)
