The Storable package brings persistence to your Perl data structures containing SCALAR, ARRAY, HASH or REF objects, i.e. anything that can be conveniently stored to disk and retrieved at a later time. It can be used in the regular procedural way by c...

Time::HiRes - High resolution alarm, sleep, gettimeofday, interval timers

59 ++

59 ++

The "Time::HiRes" module implements a Perl interface to the "usleep", "nanosleep", "ualarm", "gettimeofday", and "setitimer"/"getitimer" system calls, in other words, high resolution time and timers. See the "EXAMPLES" section below and the test scri...

Math::Trig - trigonometric functions

8 ++

8 ++

"Math::Trig" defines many trigonometric functions not defined by the core Perl which defines only the "sin()" and "cos()". The constant pi is also defined as are a few convenience functions for angle conversions, and *great circle formulas* for spher...

IO::Zlib - IO:: style interface to Compress::Zlib

4 ++

4 ++

"IO::Zlib" provides an IO:: style interface to Compress::Zlib and hence to gzip/zlib compressed files. It provides many of the same methods as the IO::Handle interface. Starting from IO::Zlib version 1.02, IO::Zlib can also use an external gzip comma...

Time::PT - objects to store an instant in time

++

++

By default, Time::PT stores time descriptions precise to 60ths- of-a-second (0.016667 seconds). The groundwork has been laid for sub-millisecond precision to be included later. This module has been adapted from the Time::Piece module written by Matt ...

Time::Piece - Object Oriented time objects
