An instance of this class represents a timezone that was specified by means of a System V timezone recipe or the POSIX extended form of the same syntax. These can express a plain offset from Universal Time, or a system of two offsets (standard and daylight saving time) switching on a yearly cycle according to certain types of rule. This class implements the DateTime::TimeZone interface, so that its instances can be used with DateTime objects.

The Carp routines are useful in your own modules because they act like die() or warn(), but with a message which is more likely to be useful to a user of your module. In the case of cluck, confess, and longmess that context is a summary of every call in the call-stack. For a shorter message you can use carp or croak which report the error as being from where your module was called. There is no guarantee that that is where the error was, but it is a good educated guess.
This package is the shared library for perl.
This module places no limit on the range of dates to which it may be applied. All function arguments are permitted to be Math::BigInt or Math::BigRat objects in order to achieve arbitrary range. Native Perl integers are also permitted, as a convenience when the range of dates being handled is known to be sufficiently small.
This module provides various type-testing functions. These are intended for functions that, unlike most Perl code, care what type of data they are operating on. For example, some functions wish to behave differently depending on the type of their arguments (like overloaded functions in C++).
