Extracting secure zone expiration date to be used for webapps

Question

Hi all,
Is it possible to extract the secure zone expiration date and use it to set the expiration date for webapps? I see that the expiration date of secure zones can be extracted through the email section, and not other places. globals.user doesn't output the expiration date either.
All that I need is the number of days so that i can automatically put the day into the Set Webapp to Expire in __ days.
Unless the webapps automatically deletes itself when users are booted out of secure zones?

I've found the module which gives the expiry date of the secure zone ie. {module_subscriptions render="collection" collection="subscriptions"}.
The output is:
  "moduleName": "subscriptions",
  "moduleDescriptor": {
  "templatePath": null,
  "parameters": "render=\"collection\",collection=\"subscriptions\"",
  "apiEndpoint": "/api/v3/subscriptions",
  "objectType": "-1",
  "objectId": "-1",
  "adminUrl": ""
  "items": [
  "entityId": 11421300,
  "zoneId": 51,
  "zoneName": "Member Only Area",
  "expiryDate": "2015-04-30T00:00:00",
  "sellAccess": "false",
  "costPerPeriod": 0.0,
  "cycleType": ""
  "params": {
  "render": "collection",
  "collection": "subscriptions"
When I use {{subscriptions.items.expiryDate}}, it doesnt output any value. I suspect that this is due to the [] encasing the items sub-information. How can I extract this information for use?
