On this system:

… I can use date
with a nanosecond precision, no problem:
$ date +'%Y%m%d%H%M%S'
20160327133441
$ date +'%Y%m%d%H%M%S%N'
20160327133446582969969
… however, if I use the same format string with moreutils
' ts
, the nanosecond precision fails:
$ ping google.com | ts '%Y%m%d%H%M%S%N'
20160327133829%N PING google.com (216.58.209.110) 56(84) bytes of data.

^C
Any way to get ts
to show nano- (or micro-) second precision when prepending timestamps to stdin?

Starting from moreutils 0.31
%.S
specifier is available, use it instead of %S :
