Dear Soeren & Co, the following stumbles in timestamps with microseconds. See:
t.info lst -g
id=lst@lst
..
creator=nik
temporal_type=absolute
creation_time=2017-10-16 09:10:15.689554
modification_time=2017-10-16 09:47:01.646840
semantic_type=mean
start_time=2013-04-13 10:00:09.935625
end_time=2017-04-24 09:57:43.257139
granularity=1 second
..
First item is:
t.rast.list lst -u column=name,start_time |head -1
lst_LC81920282013103LGN01|2013-04-13 10:00:09.935625
The error:
```
t.rast.aggregate input=lst output=lst_yearly basename=lst_yearly suffix=gran
granularity="1 year" method=average --o
0..20..40..60..80..100

Two possible updates. Remove microseconds altogether:

As ignorant as I am, I'd prefer the second. Would this cause problems to
t.* operations?
Thanks, Nikos
