Via an ingest pipeline using a processor such as a script (similar to [this](https://discuss.elastic.co/t/how-to-calculate-date-diffs-using-ingest-node/169652)) or another processor is it simple to add a field with the date x days (a field on the ingested doc) after its ingested.
Such that a doc
```auto
field: somedata
SLA: 14
```
has a field 'overdue' that is the date x days (in this example 14) from when its ingested
```auto
field: somedata
SLA: 14
overdue: x/x/21
```
Cheers

So replying to my own question again, Not tested but through digging around this is likely to be possible via the use of a script processor.
Get the field convert to millis, Instant, ZTD, then on that ZTD object a function .plusHours(x) or plusDays(x) etc ctx.SLA = ZTD object then set it as a field with the set processor.
Im sure this can be made more efficient but as a baseline this should achieve the result.
Cheers me.

This looks correct. Depending on the type of time stamp you could go with `ZonedDateTime.parse` directly or have your own custom date formatter, that can also be used to write out the date as a string again.
