My time zone setting is Kuala Lumpur, Singapore and the requestor is in Singapore. Have check 3 user see date as 20th.
The SharePoint list they see also 20th but I see date as 19th. My schedule reminder read as 19th.
Date Today both show same date: 1/11/22.
Date Picker is set to local.
Date saves in SP list show 20th to them and 19th for me.
I create document and select date as 20th, my reminder working fine. And they can see I select date as 20th not 19th.
Only when they select the date, I see it minus one day.
