The documentation about reflect.Type equality says that string equality isn't safe across packages, and you should compare the Types for equality instead. Yes, in this case, it's completely fine since we know what's going on. But let's change this so we don't erroneously copy this when doing other type comparison. See https://github.com/StackExchange/wmi/blob/51e0e53d9da457a53cfa99de75f79041ef34c5c8/wmi.go#L212 for how the wmi package fills in data, including time.Time. Let's use that pattern instead.
