A quick note:
Your milage may vary and all other the usual provisos but I've opened a sealed container of Harman Warmtone developer within the last few days, purchased in 2010 and it still works absolutely fine. The instructions state 2 years reliable life expectancy but I suspect Harman are being conservative.
