[Question]: Default time unit for Ignore events older than under datasets for System integration.

[amolnater-qasource]

Description:
While validating #3149 we have observed that we are able to save Ignore events older than field with no time units( "ns", "us" (or "µs"), "ms", "s", "m", "h") defined.

Question:
If user saves this field with only numerical data, could you please confirm what would be the default time unit for Ignore events older than field?

The underlying type of this field is Duration which is used throughout beats config, however the documentation says that type requires a unit, and I don't think I've seen it without one, so the fact that this is even possible is probably a bug.

@faec We don't support validation of a "duration" type in the UI (not supported in the package spec either for user-inputted vars). Would be a good enhancement for sure, but do you know what the effect would be if the unit is omitted in the meantime?

Hi! We just realized that we haven't looked into this issue in a while. We're sorry! We're labeling this issue as Stale to make it hit our filters and make sure we get back to it as soon as possible. In the meantime, it'd be extremely helpful if you could take a look at it as well and confirm its relevance. A simple comment with a nice emoji will be enough :+1. Thank you for your contribution!
