The put method is treating the timespan as ms.

[daniebker]

I've been trying to cache something for 65 days but noticed that the cache has been expiring and the file removed. Date.now() returns milliseconds elapsed since Jan 1st 1970 00:00: 00 UTC. So the value passed to put is actually treated as MS, not seconds. https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Date/now

Repro

1. Put an Item in the cache with seconds param set to: 5616000
2. Expected that the unix timestamp in the TTL is 1603391361815 (Oct 22, 65 days from Aug 18)
3. Actual timestamp in the cache is 2 hours later.

I can fix it locally by multiplying my value by 1000 which gives me the unix timestamp I expect.
