A time zone is attached to your RowShare account. We do our best to guess your timezone when you create your RowShare account, but we might fail at guessing. You can change the time zone at any time in the My account section.
This time zone affects when we send you reminder emails for reminder columns.
However, Date and Date/Hour columns do not take this setting into account and display exactly the value entered in the cell, regardless of each user timezone.
