Offer Advice - Need help to choose

Little background, I'm a network engineer specialised working on firewalls, routers, etc. I'm currently employed in Genpact, joined on February, on bench, hence, started finding new job. Got 2 offers, one from TCS and Corning Technologies, yes, the Gorilla Glass maker. TCS is offering me the exact same package as Genpact, no change cause I'm leaving the job in 3 months. Fair enough, I would say. Corning Technologies is a good job offer but their requirement is 247. I don't want to do 247 but I also don't wanna go to TCS. What should I do now? Also, Corning started their digital center just a year ago, so, they're new now. Product based company and much to learn but again, 247 is too much, I have done 247 earlier, it's exhausting. I don't wanna let go of a good opportunity as well. Corning has 1 month of rotation. Help me make a decision. Give me your insights. No idea about TCS working hours. I'm asking the HR but he ain't replying.
