57min is a very strange value, not related to the sdk limits in any version ...

Using the
NonOS SDK 2.2.2
Arduino 2.7.2 SDK

I have tried a simple sketch that does only this:
ESP.deepSleep(0);
it wake up after 57 minutes.

here you can find the hardware setup and the schematic.

I would try out the sketch I indicated as I found that sequence was a reliable way to start deepSleep.

Also your hook up indicates the capacative sensor is also wired to reset. Have you tried a test with this disconnected to keep it simple?

I think you should also be using schottky diodes in the feeds from GPIO16 and the sensor to reset otherwise there is a conflict of two outputs driving.
