I'm using Geektool on my Mac to display info about my computer on my desktop, plus some date and time info. I'm trying to find a script that will display a time in hours since a certain time (4.30pm, July 28, 2010).
I don't have any experience with this stuff but I have managed to find a code that can display a time in days;

python -c 'from datetime import *; print (date(2010, 07, 28) - date.today()).days'

Is there any way this can be adjusted for a time in hours?

Hi,

Try this :

# This script returns the number of hours since a certain date and time
REFERENCE_DAY=28
REFERENCE_MONTH=07
REFERENCE_YEAR=2010
REFERENCE_HOUR=16
REFERENCE_MINUTE=30
REFERENCE_SECONDS=00
REFERENCE_TS=`date -j $REFERENCE_MONTH$REFERENCE_DAY$REFERENCE_HOUR$REFERENCE_MINUTE$REFERENCE_YEAR.$REFERENCE_SECONDS +%s`

NOW=`date +%s`

echo $(( ($NOW-$REFERENCE_TS) / 3600 ))
