I've gone 7 months in a full, glass bottle. It was fine.
Thanks to all, folks !
It's really great to get help in minutes !

And for what it's worth, my Kodak Publication J-1, 6th edition, 1963, first 1965 printing gives the following "Keeping properties without use":
Full stoppered bottle: 6 months
Half-full stoppered bottle: 2 months
Tray: 24 hours
Gallon tank: 1 month
This is for storage at 65-70º 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.
