Why do you need dynamic variable names? Time and time again we get asked for this, and there's extremely rarely any good reason to do this. It's insecure and error-prone.

test::mocktime::datecalc
Test::MockTime::DateCalc(3pm) User Contributed Perl Documentation Test::MockTime::DateCalc(3pm)
NAME
Test::MockTime::DateCalc -- fake time for Date::Calc functions
SYNOPSIS
use Test::MockTime;
use Test::MockTime::DateCalc; # before Date::Calc loads
# ...
use My::Module::Using::Date::Calc;
DESCRIPTION
"Test::MockTime::DateCalc" arranges for the functions in "Date::Calc" to follow the Perl level "time" function (see perlfunc), and in
particular any fake date/time set there by "Test::MockTime". The following "Date::Calc" functions are changed
System_Clock
Today
Now
Today_and_Now
This_Year
Gmtime
Localtime
Timezone
Time_to_Date
"Gmtime", "Localtime", "Timezone" and "Time_to_Date" are made to default to the Perl-level current "time". When called with an explicit
time argument they're unchanged.
Module Load Order
"Test::MockTime" or similar fakery must be loaded first, before anything with a "time()" call, which includes "Test::MockTime::DateCalc".
This is the same as all "CORE::GLOBAL" overrides, see "OVERRIDING CORE FUNCTIONS" in CORE.
"Test::MockTime::DateCalc" must be loaded before "Date::Calc". If "Date::Calc" is already loaded then its functions might have been
imported into other modules and such imports are not affected by the redefinitions made. For that reason "Test::MockTime::DateCalc"
demands it be the one to load "Date::Calc" for the first time. Usually this simply means having "Test::MockTime::DateCalc" at the start of
a test script, before the things you're going to test.
use strict;
use warnings;
use Test::MockTime ':all';
use Test::MockTime::DateCalc;
use My::Foo::Bar;
set_fixed_time('1981-01-01T00:00:00Z');
is (My::Foo::Bar::something(), 1981);
restore_time();
In a test script it's often good to have your own modules early to check they correctly load their pre-requisites. You might want a
separate test script for that so you don't accidentally rely on "Test::MockTime::DateCalc" loading "Date::Calc" for you.
Other Faking Modules
"Test::MockTime::DateCalc" can be used with other modules which mangle the Perl-level "time" too. For example "Time::Fake",
use Time::Fake; # fakery first
use Test::MockTime::DateCalc;
Or "Time::Mock",
use Time::Mock; # fakery first
use Test::MockTime::DateCalc;
"Time::Warp" (as of version 0.5) only exports a new "time", it's not a core override and so can't be used with "Test::MockTime::DateCalc".
