Maybe another remark: The script was not desoigned for cluster, so it was good enough to reditrect the output of the script to a file.
However bash may buffer some lines before they are written. If the script is killed, that's not a problem, but if the node is fenced, you might loose the last lines(s).
So maybe you want do change the echo statement in log_time() to:
echo "$@ $t ($(date -d@"$t" -u +%F_%T))" >> your_log_file

Maybe you want to use a variable or parameter for that.
