Helmeted woman’s time in Bahrain, travelling without husband (9)
I believe the answer is:
britannia
'helmeted woman's' is the definition.
(helmet-wearing personification of Britain)
I don't understand how the rest of the clue works.
(Other definitions for britannia that I've seen before include "Figure on standard 50 pence coin" , "A monetary figure" , "In song, she used to rule the waves" , "She who musically rules the waves" , "National representative" .)
