[bug] for SRT {timestamp[absolute]} in output doesn't work?

[Gorrrg]

Ok, I used {timestamp[absolute]} and added the timestamp absolute formatting for all types as you suggested in #33. But it seems to be failing for SRT.

This from my settings.json:

        "srt": {
            "duration": 2000,
            "comments": {
                "format": "{commenter[display_name]}: {message[body]}"
            },
            "output": {
                "format": "{channel[name]} - {timestamp[absolute]} - {_id} - {title}.srt",
                "timestamp": {
                    "absolute": "%Y%m%d"
                }
            }
        }
