Update IL-RFC-30 discussion of timestamps and GeneralizedTime wrt ILP and BTP

[sappenin]

This ASN.1 definition for BTP specifies GeneralizedTime as the type for Error.triggeredAt and Prepare.expiresAt.

However, per this comment from @adrianhopebailie, no ASN.1 definitions should reference GeneralizedTime, but should instead use InterledgerTimestamps (see spec here).

Actually BTP does use Generalized Time rather than Interledger timestamps: https://github.com/interledgerjs/btp-packet/blob/master/index.js#L26-L27

Ah, yes, you're right.

So, it seems like Interledger packets use Interledger timestamps but BTP is using the special variant of GeneralizedTime (per your link above).

So, I suppose IL-RFC-30 is incorrect, then? Those rules only apply to BTP, but not to ILP packets?

Yes. It needs to be updated.

Sorry, I meant for ILP. The rationale for the switch was fixed size which is probably less relevant for BTP

[sappenin]

Makes sense - so I think the ASN definition is correct, but IL-RFC-30 needs to be cleaned up. Should I create a separate ticket and close this one?

Let's just track it here for context.
