显示已过去的时间

我想修改它来显示已经过了多少时间。

#!/bin/bash

#  Sound alarm after specifying time and message 
# Must input time delay AND message in double quotes !!
#
#       
# ** sleep can also accept intergers ex. sleep 7.63
# Made alias for it type al and time
# 2> /dev/null suppresses messages for amixer AND (c)vlc

if [ -f "$soundfile" ];
then
     echo "Soundfile is present."
else

我找到了一些可能有用的东西。但我不知道如何将我的输入集成到小时、分钟和秒字段中。
