Timed banner ( date code is giving me the wrong format)

[mns-burg]

I made a custom section for my stores sale banner, schedule the time when its removed or added.

However the end date keep getting displayed wrong.
It should be month/date/year hour:minute:second.
But it swishes the date and month. This only for the end_date part of the code.

(above what input fields)

(Above what is shown on the page) 

The liquid part:

{% assign start_date = section.settings.bsstart_time | date: "%m/%d/%Y %H:%M:%S" %}
{% assign end_date = section.settings.bsend_time | date: "%m/%d/%Y %H:%M:%S" %}
{% assign now_date = "now" | date: "%m/%d/%Y %H:%M:%S" %}

The schema part:

{
                    "type": "text",
                    "id": "bsstart_time",
                    "label": "Banner start time (optional)",
                    "info": "mm/dd/yyyy hh:mm:ss"
                },
                {
                    "type": "text",
                    "id": "bsend_time",
                    "label": "Banner end time (optional)",
                    "info": "mm/dd/yyyy hh:mm:ss"
                }

🐲💣dates in templates may be cached, "now" is NOT a reliable source of truth to disable behavior and if utilizing frontend time 💣💣 user-side-time for validation is specifically an unreliable source of time comparison (customers local browser|OS time).

Use a tool like shopify-flow to change metafields, or more advanced theme settings or files, also see more advanced tools like usemechanic app https://tasks.mechanic.dev/?q=theme%20time .

@mns-burg Join us in sanity, use YYYY-MM-DD when dealing storing date values with the ISO-8061 format https://en.wikipedia.org/wiki/ISO_8601 

{% assign end_date = "2024-11-01" | date: "%m/%d/%Y" %}

otherwise you need to use a unix timestamp, or dig into WHY ruby's strftime via liquid does this when the day value is smaller than 12  (12 months)

If using the shopify-cli is has a liquid theme console for testing logic

Maintenance Nits:  Unless using locale files label the input format AND make it clear what the expected output format is too;

Namespace fully and clearly avoiding any ambiguity for future you or other devs. 

section.settings.bsend_time should be section.settings.banner_sale_end_time  etc. it's not the 1960's needing to save 10 characters , and s + end infers "send" but nothing is being sent.
