Storing date-like metadata in DNS A record set (haven't tried other metadata cases), and reading this data out again, returns a different date-like representation of the date.

Repro code:

IAzure azure = ...;
string zoneId = ...;
var dnsZone = await azure.DnsZones.GetByIdAsync(zoneId);
var data = "2020-08-20T16:39:20";
var dnsRecordName = $"time-{DateTime.Now.ToFileTime()}";
await dnsZone
    .Update()
    .DefineARecordSet(dnsRecordName)
    .WithIPv4Address("192.168.1.1")
    .WithMetadata("test", data)
    .Attach()
    .ApplyAsync();

dnsZone = await azure.DnsZones.GetByIdAsync(zoneId);
var record = dnsZone.ListRecordSets().First(r => r.Name == dnsRecordName);
var rtData = record.Metadata["test"];
Console.WriteLine($"{data} {(data == rtData ? "==" : "!=")} {rtData}");

The above code will result in the following output:

2020-08-20T16:39:20 != 08/20/2020 16:39:20

Expected behavior:
Store "2020-08-20T16:39:20" as metadata value, then retrieve the exact same text.

Actual behavior:
Store "2020-08-20T16:39:20" as metadata value, retrieved metadata value is now "08/20/2020 16:39:20".
Azure Portal correctly shows 2020-08-20T16:39:20.

Azure Portal Screenshot, shows correct value in Portal:
