cs/Expand time format test coverage

[coderabbitai]

This issue is to track the expansion of time format test coverage as discussed in PR #1 (link) under this comment. @JarbasAl requested to open this issue for tracking.

🛠️ Refactor suggestion

Expand time format test coverage significantly.

The current coverage is minimal. Consider adding test cases for:

1. Special times:

   • Midnight (00:00)
   • Noon (12:00)
   • AM/PM transitions
   • Single-digit hours
   • Various minute combinations

2. Format variations:

   • Leading zeros
   • With/without seconds
   • Different time zones

This will ensure robust handling of all time formatting scenarios.
