Subject: Re: Workarounds for replacing self

There were a few other methods I needed - have a look:

I realise its potentially overkill making a whole new class for this, 
but some of the scripts I'm now using this in have boths times and ETAs, 
and a quick 'is_a?' allows me to distinguish them easily.
Let me know if you think you can improve it!
