Commentary
UEW considers the Ugric etymology uncertain. The etymology involves various difficulties: UEW notes that the vowel-correspondences within Mansi dialects are irregular. As this is the case, it is a wonder that the word is listed as a possible Proto-Ugric item. Also the correspondence between Mansi *γ and Hungarian *ŋ is irregular. There is no evidence here that we should assume a pre-form with *ŋ for the Mansi word.
UEW notes that the Hungarian suffix -śeg/ság probably reflects originally an independent word. This is a plausible idea, but in the light of phonological difficulties there is no reason to consider this word a cognate of the Mansi words listed in the UEW. It is also uncertain what would have been the meaning of the Hungarian word: in Hungarian there are no traces of the meaning 'time' attested in Mansi.
Conclusion
The Ugric etymology is unlikely due to both phonological and semantic difficulties.
