I have seperate audiomoths set over 3 sampling periods 8-10th March 2021, 13-15th March 2021, and 19-21st March 2021. All were set to record 10:00-19:00 (UTC). On downloading my files those recorded in the first sampling period have recorded from 10am - 6:59pm while the next two sample periods have recorded 11am - 7:59pm. All config.txt files state 10:00-19:00 (UTC) and Timezone (UTC). Any idea why there are time differences??
