Of course this is an estimate based on the script, the plot details, and basic guess-work.

Episode 1: 1 Day

According to the script, the first we see of Yaz and the Doctor after the opening, its 12:50. Then the final scene takes place the next day at 12:07. So lets say roughly 1 day (multiple times they have issues with the TARDIS).

Episode 2: 1 Days 6 Hours

Day 1 - They arrive, Yaz and Dan disapeer, Mary and the Doctor follow Svild back to the base.

Day 2 - The Doctor meets with Skaak, the battle occurs, and at the end of that day they blow up the ships, the Doctor gets Dan and they go to Atropos

Episode 3: 3 hours 3 minutes

According to the script, on Atropos they spend 1 hour 22 minutes on Time. Then an 8 minute trip to Vinder's home. Then 1 hour 33 minutes in the TARDIS before the Angel jumps out of Yaz's phone. In this hour the Doctor records the hologram for Yaz.

Episode 4: 43 Minutes

Its essentially a siege story in Jericho's basement, and the script suggests around 43 minutes. Probably one of the few episodes to be more-or-less in real time for her.

Episode 5: 5 hours.

That is at Division though, and she might've spent more time in the weeping angel form.

Episode 6: 3 hours

Roughly 1/5 of this episode the Doctors are one. For the rest of the episode, the Doctor experianced 3 different memories at once, so that is 48x3=144 minutes, so about 2 hours 24 minutes. But there is a small time skip, so lets round up to 3 hours

Overall

So at a minimum (it is likely more given multiple time skips, and the inevitable adventure taking place in between moments like when they go from Atropos to Medderton, or while the Doctor is an Angel)...

Flux for the Doctor takes place over 66 hours (rounded up). 66 hours no sleep or rest where she experiences a doomsday event, becoming a weeping angel, meeting a past companion, discovering more mysteries surrounding herself, meets her abusive adoptive mother, and eventually growing as a person by moving on from all that grief.

Yes, that is supposed to be Yaz.

With the recently-released @doctorwho_magazine containing this #whitewashed portrayal of South Asian companion Yasmin Khan, it’s no wonder there’s backlash on social media. White-washing is not new, but it is harmful— and it’s always racist. Accountability matters. 

"Hey," Yaz says as she walks over to the Doctor. The Doctor had been sitting there on the steps in the console room in silence for the past few hours. Her mind shooting around thoughts of what she could've done better, something, anything she could've done for Ryan and Graham to stay.

She slowly looks up at her remaining companion. "Hey." She says dully with a short, half-hearted smile. She then turns her attention back to the floor and to her never-ending punishment of thoughts.

She'd been through too much. He lost his companion, Bill, she was dead and gone and he'd never see her again. Then, he regenerated, an event that always causes pain and confusion and always at a time when the world seems to be ending. Then she found out she was a woman now, not that she minded, in fact she found it rather facinating and comfortable. Then she made some friends -new companions- except, like always, she grew too attached. And, like always, wasn't open with them, too scared of sharing her built up pain. She was already vunerable and worried she'd scare them off.

And then... she lost Galifrey all over again. This time, she lost it all to the Master's hands. Yet she still found it in herself to understand him and feel sorrow for him. After all, she loved him, they had been friends of sorts for as long as she could remember. As it turns out, it wasn't necessarily that long.

Now she had to deal with not knowing who she was as well as everything else. As well as losing two of her family, because she'd almost died, been sent to jail and then returned with a stiff and edgy welcome.
