[BUG] TC_EEVSE_2_3 does not run on EST timezone

[andy31415]

Reproduction steps

Running something of the form:

scripts/run_in_python_env.sh out/venv './scripts/tests/run_python_test.py --load-from-env out/test_env.yaml --script src/python_testing/TC_EEVSE_2_3.py'

fails on my machine with:

The comparison of times seem to be timezone dependent. This prevents me from being able to "run all CI tests" on my machine.

Specifically setting TZ=UTC makes the test pass however setting TZ=EST causes the faiulure for me.
