@JeffSilberberg Please see under usage notes for additional details about what parameters are available, and what parameters they can be applied to:
"The POST body, URL parameters, and Custom headers parameters can use feed global variables. By default, the feed global variables are converted into epoch time (milliseconds since January 1, 1970 UTC). Optionally, you can convert the feed global variables to epoch seconds (seconds since January 1, 1970) and a desired string date time format. The following outlines the feed analytic variables and the time they represent.
- $feed.FeedStartTime—The time the feed was started
- $feed.FeedScheduledStartTime—The time the next recurrence of the feed is scheduled
- $feed.FeedLastScheduledStartTime—The time the last recurrence of the feed was scheduled"
There is additional documentation on this page linked from Global Variables:
"For more information on setting a date format (epoch milliseconds, epoch seconds, and string format), see Date and time parameters."

I hooked up a quick example with screenshots below of what this configuration would look like to reference the FeedLastScheduledStartTime global variable:
