The Radar Time Select module allows fast, efficient display of historical WSR-88D (American) radar information, often going back to 2 or 3 weeks.
When this menu is chosen you will see the following panel:
If "Use current (real-time) radar data" is enabled, Digital Atmosphere will function normally.
If it is disabled, then Digital Atmosphere will use the date and time shown to find archived radar information online whenever a product is chosen in the Radar menu. The Preferences > General > Radar Source dropdown must be set to a designated radar archive source, and that source must be configured properly in the digatmos.rad file.
