timestamp

func Now ¶

func Now() time.Time

Now returns a time.Time that closely approximates Microsoft's server time, suitable for inclusion in a signed Xbox Live request.

If Update has been called with a valid 'Date' response header, the cached delta is applied to the current local time to compensate for clock skew. Signed requests are rejected if the timestamp in the signature differs too much from the server time.

func Update ¶

func Update(header http.Header)

Update computes the delta between the local clock and Microsoft's server time using the 'Date' header of an HTTP response, and caches it for later use by Now. If the header is absent or cannot be parsed, the cached delta is left unchanged.
