ODK Collect/Aggregate and time zones

1. What is the problem? Be very detailed.
I thought I had read that ODK Aggregate converted timestamps from ODK Collect into UTC for storage. However, the today field seems to store the time as it was collected on the form. Can you confirm that the today field stores user input with no conversion?

2. What app or server are you using and on what device and operating system? Include version numbers.
ODK Collect (version varies per tablet) stored on ODK Aggregate 1.4 (yes this is old)

3. What you have you tried to fix the problem?

4. What steps can we take to reproduce the problem?

5. Anything else we should know or have? If you have a test form or screenshots or logs, attach below.
