While attempting to use the formula =IF(A2<>"",IF(B2<>"",B2,NOW()),"") , to automatically enter a date/time stamp when making any entry in the adjacent cell. The formula was created and tested using the local desktop version of Microsoft Excel and works fine. However, after creating the Excel Tab in Teams and opening the spreadsheet, we are given three options for editing the spread sheet. When selecting either the "Edit in Teams" or the "Edit in Excel Online" options the formula returns Pacific Standard Time. If you select to "Open in Excel" using the local desktop version the formula returns Eastern Standard Time (which is intended for our purposes). Is there a setting somewhere that I am missing so that EST is the default for all methods of edit?
