Write the set of time zones maintained by the specified `loader` to the specified output `stream` in a single‐line format, and return a reference to `stream`. If `stream` is not valid on entry, this operation has no effect. Note that this human‐readable format is not fully specified, can change without notice, and is logically equivalent to: ` print(stream, 0, ‐1); `
