Hi Punter

I have answered your question below.

Difference between Timed based and number based manifests in mpeg dash output?
Can I ask what product you are referring to?

The media attribute in the SegmentTemplate properties defines the URL where playback devices send segment requests. For number based manifest, the URL uses a $Number$ variable to identify the specific segment that is requested. When a playback device requests the segment, it replaces the variable with the number identifier of the segment.

For time based manifest, uses the $Time$ variable instead of $Number$ in the URL of the media attribute.

For your information, you can read our DASH media Attribute in SegmentTemplate for MediaPackage.
https://docs.aws.amazon.com/mediapackage/latest/ug/segtemp-format-media.html

What are its advantages ?
It depends on what format your player supports. Number based manifest is more common then time based manifest.

does hls also support this ?
No, this is specific for DASH. HLS has a different manifest structure.

Looking at Akamai's Encoder guide, the example they provided is a DASH Number with Duration manifest.

If you are having any issue streaming to Akamai with our AWS Elemental appliance products, you can raise a support case and we can follow up with you.

Thanks,
