+### UTC
+All dates and times are stored at the server in UTC (GMT) values.  The server has no knowledge of time zones so this value is used to display the time and date in your local Browser time zone.
+While you can ovveride this setting it's generally best to allow it to be the default setting obtained from the browser itself.
+
+### Filtering dates
+When viewing data in AyaNova that is filtered with one of the relative date filters (for example a filter of "TODAY"), this time zone setting is taken into account in order to ensure that the user sees data appropriate to *their time zone*.  This means that two people with browsers in different time zones using a filter of TODAY for a date field may see different list of results from each other.
