Hello,
date options should precede the format string.
% date -u +'%Y-%m-%d %T' -d @100000
date: Expected digit in canonical time
date: -d
date: ^
Usage: date [-ajnu] [-d date] [-r seconds] [+format]
[[[[[[CC]yy]mm]dd]HH]MM[.SS]]
% date -u -d @100000 +'%Y-%m-%d %T'
1970-01-02 03:46:40
Possibly the first example is trying to set the system time to '-d'.
Here's patch to guile-2.0.14.
Thanks,
