Change time format and add time

[justin1977 (Justin Saunders)]

@petro

{% set h, m = value.strip().split(':') %}
{% set h, m = [ h, m[:2] ] | map('int') %}
{% set t = now().replace(hour=h, minute=m, second=0).timestamp() + 4 * 60 * 60 %}
{{ t | timestamp_custom('%H:%M:%S') }}

Great! That works. Thank you @petro. I would have never figured that out on my own.
