Problem with (Understanding) function

I have this code

Code:
#!/bin/bash

LZ () {
RETVAL="\n$(date +%Y-%m-%d_%H-%M-%S) --- "
return RETVAL
}

echo -e $LZ"Test"
sleep 3
echo -e $LZ"Test"

which I want to use to make logentrys on my NAS. I expect of this code that there would be output like

Code:
2017-03-07_11-00-00 --- Test

2017-03-07_11-00-03 --- Test

But I get (without the three seconds difference)
Code:
2017-03-07_11-00-00 --- Test

2017-03-07_11-00-00 --- Test

Who knows the solution of my problem? I thank you for every hint and help.

NAME
Test::Requires - Checks to see if the module can be loaded SYNOPSIS
# in your Makefile.PL use inc::Module::Install; test_requires 'Test::Requires'; # in your test use Test::More tests => 10; use Test::Requires { 'HTTP::MobileAttribute' => 0.01, # skip all if HTTP::MobileAttribute doesn't installed }; isa_ok HTTP::MobileAttribute->new, 'HTTP::MobileAttribute::NonMobile'; # or use Test::More tests => 10; use Test::Requires qw( HTTP::MobileAttribute ); isa_ok HTTP::MobileAttribute->new, 'HTTP::MobileAttribute::NonMobile'; # or use Test::More tests => 10; use Test::Requires; test_requires 'Some::Optional::Test::Required::Modules'; isa_ok HTTP::MobileAttribute->new, 'HTTP::MobileAttribute::NonMobile'; DESCRIPTION
Test::Requires checks to see if the module can be loaded. If this fails rather than failing tests this skips all tests. Test::Requires can also be used to require a minimum version of Perl: use Test::Requires "5.010"; # quoting is necessary!! # or use Test::Requires "v5.10"; AUTHOR

If the "RELEASE_TESTING" environment variable is true, then instead of skipping tests, Test::Requires bails out. SEE ALSO
