[SOLVED] date +T%T.%N

I am using date as follows

Code:

date +T%T.%N

What does the + signify?

date [OPTION]... [+FORMAT]

Basically because it is syntax specific to the date command which indicates the start of the desired output format.

Let me define a function as follows

Code:

time-stamp ()
 {
  if (( $# == 0)); then
    tmstamp="$(date +T%T.%N)"
  else
    tmstamp="$(date $1)"
  fi
  echo "$tmstamp"
 }

What would be the optimal way to call the function with a format?

Code:

stamp="$( time-stamp +T%T.%N )"

Should one quote (double or single) the format with "+T%T.%N" or '+T%T.%N'?

You marked the thread as solved, however..

It does not mater if you use single or double quotes.

Code:

stamp=$( time-stamp "+T%T.%N" )
