I was unsure about some results of the $alamanac tag. So I created a test template. It is very short. It calculates the sunrise time for June 21st, 2022:
$current.dateTime , $almanac(almanac_time=1655805600).sunrise Every archive period a file is created out of that template. And I collected those files. I would expect to get the same sunrise time all the time. But I don't. Could someone explain the reason for that behavior? The different files for the different archive periods are (one line per file): 03.11.2022 15:40:00 , 04:52:07 03.11.2022 15:45:00 , 04:52:07 03.11.2022 15:50:00 , 04:52:06 03.11.2022 15:55:00 , 04:52:06 03.11.2022 16:00:00 , 04:52:06 03.11.2022 16:05:00 , 04:52:06 03.11.2022 16:10:00 , 04:52:06 03.11.2022 16:15:00 , 04:52:05 03.11.2022 16:20:00 , 04:52:05 03.11.2022 16:25:00 , 04:52:05 03.11.2022 16:30:00 , 04:52:05 03.11.2022 16:35:00 , 04:52:05 03.11.2022 16:40:00 , 04:52:05 03.11.2022 16:45:00 , 04:52:05 03.11.2022 16:50:00 , 04:52:04 03.11.2022 16:55:00 , 04:52:04 03.11.2022 17:00:00 , 04:52:04 03.11.2022 17:05:00 , 04:52:04 03.11.2022 17:10:00 , 04:52:04 03.11.2022 17:15:00 , 04:52:04 03.11.2022 17:20:00 , 04:52:04 03.11.2022 17:25:00 , 04:52:04 03.11.2022 17:30:00 , 04:52:04 03.11.2022 17:35:00 , 04:52:04 03.11.2022 17:40:00 , 04:52:04 03.11.2022 17:45:00 , 04:52:04 03.11.2022 17:50:00 , 04:52:04 03.11.2022 17:55:00 , 04:52:03 03.11.2022 18:00:00 , 04:52:03 03.11.2022 18:05:00 , 04:52:03 03.11.2022 18:10:00 , 04:52:03 03.11.2022 18:15:00 , 04:52:03 03.11.2022 18:20:00 , 04:52:03 03.11.2022 18:25:00 , 04:52:03 03.11.2022 18:30:00 , 04:52:03 03.11.2022 18:35:00 , 04:52:03 03.11.2022 18:40:00 , 04:52:04 03.11.2022 18:45:00 , 04:52:04 03.11.2022 18:50:00 , 04:52:04 03.11.2022 18:55:00 , 04:52:04 03.11.2022 19:00:00 , 04:52:04 03.11.2022 19:05:00 , 04:52:04 03.11.2022 19:10:00 , 04:52:04 03.11.2022 19:15:00 , 04:52:05 03.11.2022 19:20:00 , 04:52:04 03.11.2022 19:25:00 , 04:52:05 03.11.2022 19:30:00 , 04:52:04 03.11.2022 19:35:00 , 04:52:05 03.11.2022 19:40:00 , 04:52:05 03.11.2022 19:45:00 , 04:52:05 03.11.2022 19:50:00 , 04:52:05 03.11.2022 19:55:00 , 04:52:05 03.11.2022 20:00:00 , 04:52:05 03.11.2022 20:05:00 , 04:52:05 03.11.2022 20:10:00 , 04:52:05 03.11.2022 20:15:00 , 04:52:05 03.11.2022 20:20:00 , 04:52:05 03.11.2022 20:25:00 , 04:52:05 03.11.2022 20:30:00 , 04:52:05 03.11.2022 20:35:00 , 04:52:05 03.11.2022 20:40:00 , 04:52:05 03.11.2022 20:45:00 , 04:52:05 03.11.2022 20:50:00 , 04:52:05 03.11.2022 20:55:00 , 04:52:04 03.11.2022 21:00:00 , 04:52:04 03.11.2022 21:05:00 , 04:52:04 03.11.2022 21:10:00 , 04:52:04 03.11.2022 21:15:00 , 04:52:03 03.11.2022 21:20:00 , 04:52:03 03.11.2022 21:25:00 , 04:52:03 03.11.2022 21:30:00 , 04:52:02 03.11.2022 21:35:00 , 04:52:02 03.11.2022 21:40:00 , 04:52:02 03.11.2022 21:45:00 , 04:52:02 03.11.2022 21:50:00 , 04:52:02 03.11.2022 21:55:00 , 04:52:02 03.11.2022 22:00:00 , 04:52:02 03.11.2022 22:05:00 , 04:52:02 -- You received this message because you are subscribed to the Google Groups "weewx-user" group.
