If you ever have a need to display something like:

"last update 5 days ago" "user logged in 2 mins ago"

you can use this script to determine how long ago a timestamp is versus now().

It is different. It's a 'fuzzy' ouput. Timesince give you '3 days, 1 hour ago'. This would just give you '3days'.

register = template.Library()

@register.filter
