Time drift in Thursby area, anyone else losing about 20 minutes on Wednesdays? (Thursby Flats)

Third Wednesday in a row where I've arrived at work about 20 minutes later than my commute should allow. Same route, same departure time, no delays. I'm just arriving later than the math says I should.

Checked with two coworkers who also live in Thursby and they're both experiencing it. Only on Wednesdays. Only about 20 minutes. One of them said she's been setting her clocks forward to compensate but that just means she loses the 20 minutes at home instead, which she described as "worse somehow."

Filed a drift report with the Temporal Standards Office. They said Thursby is "within acceptable variance" and that anything under 45 minutes per occurrence doesn't qualify for an investigation. They suggested keeping a log, which I am, and it's the most boring log you've ever seen because every entry just says "Wednesday. 20 minutes. Again."

Has anyone in the area figured out a workaround? I just want my Wednesdays back. All of them.
