What is the proposed idea/solution?
Allow us to select a timezone for datetime fields that only show a date.
How does this solve the user problems?
There is currenly a disconnect between Interface date filters (ie. filter Where {Date Field} is Today) which will filter based on a local timezone, but inside the base, the date-only field is GMT. So, the interface will filter based on local timezone, but records in the base will be GMT-based dates, and will be filtered out, even if the date is the same as the local timezone.
How was this validated?
By beating my head into the brick-wall that is Date-based filters
Who is the target audience?
Anyone who uses the filter based on 'Today'.
