FAQ
Questions Timezone Fast Shifter owners ask.
- 01
How does the capability handle timezone changes?
The calculate_fast_window_shift capability calculates the total elapsed time from your fast start to arrival, then adjusts for the destination's UTC offset to provide a new feeding window.
- 02
What does it mean if my fast is 'broken'?
A broken fast occurs when the timezone shift causes your scheduled feeding window to start earlier than originally planned, potentially forcing you to eat prematurely.
- 03
Can I check if my flight schedule is valid for fasting?
Yes, you can use validate_travel_timeline to ensure your feeding start time and flight departure are logically compatible.
