The available time resolution varies by our data product categories, and you can find the options in our API Toolkit.  For quick reference, here are some numbers to keep you moving as you explore our data further! 

All Solcast API data values are period averages, timestamped in UTC at the end of the averaging period (e.g. data from 1100 to 1130, for 30 minute average, would be timestamped at 1130).
