Cannot create subscription with timestamp using Stripe API

Question

Background

I have a script that creates subscriptions for customers using the Node.js Stripe API.

Code

After reading the documentation on how to create subscriptions I have arrived at the following code:

var stripe = require( "stripe" )( "my_TestKey" );

stripe.subscriptions.create({
    "customer":"myCustomer",
    "billing":"charge_automatically",
    "trial_end":"1509186774",
    "items": [ {"plan":"mySubscription"} ] 
})
.then( console.log )
.catch( console.error );

Problem

However, this subscription fails with the following error:

"error":{"type":"StripeInvalidRequestError","stack":"Error: Invalid timestamp: must be an integer Unix timestamp in the future.\n at Constructor._Error ...

What I tried

So, I assumed that my error was in the trial_end field, and so I double checked the timestamp in the following websites:

• https://www.epochconverter.com/
• https://www.unixtimestamp.com/index.php

Which both convert it successfully to a date. I also tried making the request with the date in milliseconds but then it obviously didn't work.

Question

• What am I missing? Why is stripe considering that field a non-valid one?

Answer 1

The timestamp 1509186774 is for Saturday, 28 October 2017. The trial_end parameter must for a date in the future — maybe you meant to use 28 October 2018, which is 1540722774.
