-//UnixTimeReadonly is a helper type that provides type-safe access to a Swift
-//header whose value is a UNIX timestamp. It cannot be directly constructed,
-//but some subtypes of schwift.Headers have fields of this type. For example:
-//
-// var hdr AccountHeaders
-// //hdr.Timestamp is a headers.UnixTimeReadonly instance
-// hdr.Timestamp.Get() //returns a time.Time
-// hdr.Get("X-Timestamp") //returns a string containing a UNIX timestamp
-// //refering to the same point in time
-type UnixTimeReadonly struct {
- Base
-}
-
-//Exists checks whether there is a value for this header.
-func (f UnixTimeReadonly) Exists() bool {
- return f.H.Get(f.K) != ""
-}
-
-//Get returns the value for this header, or the zero value if there is no value
-//(or if it is not a valid timestamp).
