Yes, this is always the case with google sheets. Glide Tables are more of a true database, which has proper date type columns. Google Sheets store dates as text, so I think it’s harder for glide to determine true timezones. If I were to venture a guess, Glide tables always store the underlying UTC time and the conversion is handled to display in the users local time. But in google sheets, the time is stored as if it’s the users local timezone, so there is no conversion.
