Summary

  • Reduce temporal fuzz test configurations from 72 to 10
  • INT96-specific settings (int96AsTimestamp, int96TimestampConversion) now only tested for INT96 format
  • Reduced timezones from 3 to 2 (local + UTC)
  • Removed inferTimestampNtzEnabled loop (not relevant for this test's focus)
  • Added TimestampType column to properly exercise timestamp settings

Test plan

  • Ran CometFuzzTestSuite temporal tests - all pass
  • Temporal test time reduced by ~5x

🤖 Generated with Claude Code

The temporal tests had 72 configurations (3 output types × 3 timezones ×
2 × 2 × 2 settings), reduced to 10 configurations:
- INT96: 2 timezones × 3 int96 combinations = 6 configs
- TIMESTAMP_MICROS/MILLIS: 2 timezones × 1 combination = 2 configs each

Key changes:
- INT96-specific settings only tested for INT96 format (where they matter)
- Reduced timezones from 3 to 2 (local + UTC)
- Removed inferTimestampNtzEnabled loop (not relevant for this test)
- Added TimestampType column to properly exercise timestamp settings

This reduces temporal test time by ~5x.
