If you want to get fine-grained data in a larger time range, you will need to specify the time ranges and make multiple requests for multiple times.If you’ve specified only the start time in your request, the system will return 500 pieces of data from the specified start time to the current time of the system; if only the end time is specified, the system will return 500 pieces of data closest to the end time; if neither the start time nor the end time is specified, the system will return the 500 pieces of data closest to the current time of the system.
