How long is both games for Chell?

Roughly how much time does Chell experience across both games. I phrase it like that, because I wouldn’t include the period of time in which she was in cryogenic freezing, because that could be between like 10 years and 70,000 or something ridiculous.

I was just wondering how much time Chell would’ve experienced inside Aperture solving test chambers and thinking with portals.
