Feature request: render "Expiration" field of Offers in transaction explainer

[mDuo13]

Some offers, like this one, seem very mysterious ("success" without doing anything?):

https://www.ripplecharts.com/#/transactions/A6D429DFA83CC2752379203880A680431321F7FDBB6D114E2817D22E10509460

The solution to the mystery is that the offer has an expiration date that's in the past. There are a couple ways the Charts transaction explainer could improve this:

1. Show the Expiration time in the "Description" tab.
2. In the "Raw" tab, show the Expiration field's value in ISO format (in addition or instead of showing it in seconds since the Ripple epoch)

So Expiration is a ripple Epoch timestamp?

Yes - same as the ledger timestamp.
