### Friends

class **tzdb\_list**\

## Detailed Description

An iterator into the tzdb\_list

As a extension, in libstdc++ each tzdb is reference-counted and the const\_iterator type shares ownership of the object it refers to. This ensures that a tzdb erased from the list will not be destroyed while there is an iterator that refers to it.
