Hi!
Welcome to Microsoft Q&A forum.
To fix the time and date for Windows 11, you need to change the time zone and allow Windows to find it automatically.
Go to Start > Settings > Time & Language > Date & Time.
For Time Zone:
Allow Windows to determine automatically by clicking Set time zone automatically to On. Manually choose your time zone by clicking Set time zone automatically to Off and choosing your time zone from the Time Zone drop-down menu. For Texas, select (UTC-06:00) Central Time (US & Canada).Set time automatically should be turned on as well.
