Save yourself a bunch of overhead by calling date once:
Code:
#!/bin/ksh

# save date output in a variable.
todaysdate=$(date)

# Parse the elements into their own variables.
print $todaysdate|read dw mo da time zn yr

print $dw $mo $da $time $zn $yr

# If you really need the time elements split out:
OLDIFS=$IFS
IFS=:
print $time|read hr mn sc
IFS=$OLDIFS

print $hr $mn $sc

The read command will parse on the Input Field Seperator.

lr_environment

LR_ENVIRONMENT.IN(1)					  LogReport's Lire Documentation				      LR_ENVIRONMENT.IN(1)

NAME

       lr_environment - Export Lire configuration in shell script form

SYNOPSIS

       eval `lr_environment`

DESCRIPTION

       The lr_environment command is used to import the Lire configuration in Lire shell scripts.

       All of Lire configuration variables will be written in a format that can be evaled by the shell.

       Shell scripts don't usually have to use that command, since it is done by the defaults file sourced by each command.

       The old names used by when the configuration was done in shell script are also exported by this script for backward compatibility.
