date enhancement - filter to preface each line of input with timestamp

[Evan Rempel]

There is a lot of discussion on the net about prefacing a timestamp to
every line of a text stream. There are solutions with awk, perl, python
and bash. coreutils even provides one using perl. This seems to be a
very heavy tool to do something that date already does all of the hard
work for.

Does it make sense to add an option -p --prefix to make date prefix
every line of stdin with a date/time stamp?

Thanks.
