Feature Request: Configurable Time Rounding per Project

[xdespujols]

Summary

Add an option to round tracked time entries to configurable intervals (15 min, 30 min or 1 h) on a per-project basis.

Motivation

Some teams prefer to log time in fixed increments rather than exact minutes, to simplify reporting and billing. Allowing each project to define its own rounding rule would increase flexibility and better match clients’ invoicing policies.

Proposal

In the project settings, add a “Time Rounding” dropdown with options:

• No rounding (current behavior)
• Round to nearest 15 minutes
• Round to nearest 30 minutes
• Round to nearest 1 hour
• Apply rounding when the user saves or exports time entries for that project.

Ensure the change is clearly noted in exports and API responses (e.g. an extra field "rounded_duration").

Example

• Entry of 1 h 07 min on Project A (configured to 15 min) → stored/exported as 1 h 00 min
• Entry of 1 h 07 min on Project B (configured to 30 min) → stored/exported as 1 h 00 min
• Entry of 1 h 40 min on Project C (configured to 1 h) → stored/exported as 2 h 00 min

Additional Context

• This feature would help teams align time tracking with their billing cycles and reduce manual adjustments after the fact.
