Can one write
a. The attacks when I was at the hospital were mild.
b. The attacks during my stay at the hospital were mild.
?
In these sentences 'when I was at the hospital' and 'during my stay at the hospital' are supposed to be time clauses that postmodify 'the attacks' restrictively. They are supposed to be adjectival.
The sentences are supposed to mean:
The attacks that occurred when I was at the hospital/during my stay at the hospital were mild.
Maybe there were other attacks that occurred elsewhere and were not mild.
Would you say the sentences work with that meaning?
Many thanks
