Machine Type: i686-redhat-linux-gnu

Bash Version: 3.2
Patch Level: 33
Release Status: release

Description:
The script below fails on my box with the following output:

1197676800
date: invalid date `1970-01-01 \033[?1034h1197676800 sec'

So for some reason the value passed to date got a nasty prefix.

I guess this could be charset-related, so here's my locale

LANG=en_US
LC_CTYPE="en_US"
LC_NUMERIC="en_US"
LC_TIME="en_US"
LC_COLLATE="en_US"
LC_MONETARY="en_US"
LC_MESSAGES="en_US"
LC_PAPER="en_US"
LC_NAME="en_US"
LC_ADDRESS="en_US"
LC_TELEPHONE="en_US"
LC_MEASUREMENT="en_US"
LC_IDENTIFICATION="en_US"
LC_ALL=

Repeat-By:
executing this script

#!/bin/bash
let "STEP=86400"
let "CALCTIME=`date +%s`"
export DAYSTART=`echo "$CALCTIME - ($CALCTIME % $STEP) - 
$STEP" |bc -i |tail -1`

echo "$DAYSTART"
export BASHBUG=`date -d "1970-01-01 $DAYSTART sec" +"%Y-%m-%d %T"`

Fix:
Yes, please ;)

I cannot recreate the problem.  However I think your issue is because
you are forcing bc into interactive mode.

Ok, thanks guys, you are both right, the interactive mode was the 
cause for this. how could i ever doubt the purity of the bash :)

Br,
