ttl for route53 should be sent as seconds

[kwypchlo]

👋

I'm using caddy to request certificates through route53 provider

{
  "module": "acme",
  "challenges": {
    "dns": {
      "provider": {
        "name": "route53"
      },
      "ttl": "1h"
    }
  }
}

unfortunately it seems like the ttl of 1 hour is translated to 3600000000000 while the dns errors out saying that max is 2147483647

{
  "level": "error",
  "ts": 1632395039.5339599,
  "logger": "tls.obtain",
  "msg": "will retry",
  "error": "[siasky.dev] Obtain: [siasky.dev] solving challenges: presenting for challenge: adding temporary record for zone siasky.dev.: InvalidInput: InvalidInput: 1 validation error detected: Value '3600000000000' at 'changeBatch.changes.1.member.resourceRecordSet.tTL' failed to satisfy constraint: Member must have value less than or equal to 2147483647\n\tstatus code: 400, request id: 21b98755-2e7b-47f8-abad-d8eb24207a81 (order=https://acme-staging-v02.api.letsencrypt.org/acme/order/27549458/598268258) (ca=https://acme-staging-v02.api.letsencrypt.org/directory)",
  "attempt": 2,
  "retrying_in": 120,
  "elapsed": 63.129179538,
  "max_duration": 2592000
}

seems to me there should be some conversion going on for route53 so that the number is sent as seconds so 3600 instead of 3600000000000

TTL (seconds)
The amount of time, in seconds, that you want DNS recursive resolvers to cache information about this record. If you specify a longer value (for example, 172800 seconds, or two days), you reduce the number of calls that DNS recursive resolvers must make to Route 53 to get the latest information in this record. This has the effect of reducing latency and reducing your bill for Route 53 service. For more information, see How Amazon Route 53 routes traffic for your domain.

Actually I'm not sure whether it's this plugin concern or caddy itself - @mholt is this expected number format ?

[mholt]

Caddy feeds the plugins a time.Duration value as defined by the libdns APIs, which is a number of nanoseconds. If the provider expects seconds, the plugin will need to do the conversion.
