Java A Question Regarding Timers and Output
Hi there. I am fairly new to scripting in BASH so please forgive my clumsy syntax and analogy as I try to explain what I am trying to accomplish.

I have a list of mundane functions that I currently call from a script file. What I wish to do is to accurately record into a log file the times that each step is taking to allow for some analysis and planning of resources as I utilize the script for more activity on more machines. I have been directed to look at the time function but find that it's usefulness is very limited if I wish to contain all of my data to one output file. Please see the example below of my understanding of how to utilize it.
Code:
/usr/bin/time -o 'output file path' 'command to execute'

However, what I wish to see is something more like the result from what code I was able to cobble together below.
Code:
LOGFILE=completed_work_`date +%F`.log
my_run_start_date=`date +%F`
my_run_start_time=`date +%H:%M`
    echo Run began on $my_run_start_date at $my_run_start_time >> $LOGFILE
master_start=`date +%s`
# do the work here
step_start=`date +%s` #timer start
    echo 1 Do some work here.;echo 1 This is what we did here. >> $LOGFILE
step_end=`date +%s` #timer end
    step_diff=`expr $step_end - $step_start`
    echo How long it took to do it : $step_start - $step_end = $step_diff >> $LOGFILE
# we can do this as many times as we need to
step_start=`date +%s` #timer start
    echo 2 Do some work here.;echo 2 This is what we did here. >> $LOGFILE
step_end=`date +%s` #timer end
    step_diff=`expr $step_end - $step_start`
    echo How long it took to do it : $step_start - $step_end = $step_diff >> $LOGFILE
# end of the work section
master_end=`date +%s`
master_diff=`expr $master_end - $master_start`
my_run_end_date=`date +%F`
my_run_end_time=`date +%H:%M`
    echo Run ended on $my_run_end_date at $my_run_end_time >> $LOGFILE
    echo Start=$master_start : End=$master_end >> $LOGFILE
master_time_elapsed=`expr $master_diff / 3600`
    echo Elapsed time = $master_time_elapsed hours >> $LOGFILE

Can anyone please assist me with a more concise and/or elegant approach to accomplishing this within a mixed Unix/Linux environment?

env

env(1)								   User Commands							    env(1)

NAME

       env - set environment for command invocation

SYNOPSIS

       /usr/bin/env [-i | -]  [name=value...] [ utility [ arg... ]]

       /usr/xpg4/bin/env [-i | -]  [name=value...] [ utility [ arg... ]]

DESCRIPTION

       The  env utility obtains the current environment, modifies it according to its arguments, then invokes the utility named by the utility op-
       erand with the modified environment.

       Optional arguments are passed to utility. If no utility operand is specified, the resulting environment is written to the standard  output,
       with one name=value pair per line.

   /usr/bin
       If env executes commands with arguments, it uses the default shell /usr/bin/sh (see sh(1)).

   /usr/xpg4/bin
       If env executes commands with arguments, it uses /usr/xpg4/bin/sh (see ksh(1)).

OPTIONS

       The following options are supported:

       -i | -	       Ignores the environment that would otherwise be inherited from the current shell.  Restricts the environment for utility to
		       that specified by the arguments.

OPERANDS

       The following operands are supported:

       name=value      Arguments of the form name=value modify the execution environment, and are placed into  the  inherited  environment  before
		       utility is invoked.

       utility	       The name of the utility to be invoked.  If utility names any of the special shell built-in utilities, the results are unde-
		       fined.

       arg	       A string to pass as an argument for the invoked utility.

EXAMPLES

       Example 1: Invoking utilities with new PATH values

       The following utility:

       example% env -i PATH=/mybin mygrep xyz myfile

       invokes the utility mygrep with a new PATH value as the only entry in its environment. In this case, PATH is used to locate  mygrep,  which
       then must reside in /mybin.

ENVIRONMENT VARIABLES

       See  environ(5)	for  descriptions of the following environment variables that affect the execution of env: LANG, LC_ALL, LC_CTYPE, LC_MES-
       SAGES, and NLSPATH.

       PATH	Determine the location of the utility. If PATH is specified as a name=value operand to env, the value given shall be used  in  the
		search for utility.

EXIT STATUS

       If  utility  is invoked, the exit status of env is the exit status of utility. Otherwise, the env utility returns one of the following exit
       values:

       0	Successful completion.

       1-125	An error occurred.

       126	utility was found but could not be invoked.

       127	utility could not be found.

ATTRIBUTES

       See attributes(5) for descriptions of the following attributes:
