User language makes date format different when saves to DB

Hi Guys, 

As the user's language can be set as English (US) and English (UK), and this will make the date format different when using the function now():

US format :   14/2022 6:36 AM GMT+00:00(Date and Time with Timezone)
UK format:    14/03/2022 06:36 GMT+00:00(Date and Time with Timezone)

and this will cause these two format's date save into DB (based on my current PM design) which will cause my following work flow (such as micro service retrives the date from DB) goes wrong when using these data.

I tried to transfer the date by using such method:

{
  todate(datetext(todate(now()), "DD/MM/YYYY"))
}

Date out of range (73032022)(Date with Timezone)

So I'm wondering if there is any method can resolve this issue, thanks
