Hi, 

Any update on changing the timestamps you’re sending to Customer.io via the direct integration from ISO to Epoch? I asked in this post before: 

Customer.io doesn’t run on ISO, they use Epoch. As it stands, this integration isn’t very useful (the most important piece of data that I need in Customerio is the user’s expiration date!).

Hi! I am following up on this internally, but in the mean time and in case you had not seen this documentation, I found this documentation from Customer.io on updating attributes to Epoch on their end if they are not added in that format originally: https://docs.customer.io/journeys/how-to-use-attribute-updates-to-reformat-timestamps/

@wes_clark Oh that’s interesting, I hadn’t seen that. Pretty nifty! And thanks for following up internally.
