    Thanks. The one I have is from 1977.

    Half-full stoppered bottle: 2 months
    Tray: 24 hours
    Gallon tank: 1 month
    This is for storage at 65-70 F, higher storage temperatures will give shorter life. And "The figures given in this table are estimates based on experience and are intended for use only as a guide."

    This is on page 30 of my edition of Kodak Professional Data Book J-1, Processing Chemicals and Formulas for Black-and-White Photography

    BTW Michael R., thank you for citing your source, guessing we have different editions as our page numbers differ.

    It turns very brown and smells like sour rotten eggs over time... Then it is bad...
