Convert and Verify Unix Timestamps During Debugging
When this applies
Use this workflow when auth expiry, scheduling, or logs look inconsistent. Convert timestamps and validate units and timezone assumptions.
Tool to use
Convert Unix timestamps to dates.
Open Unix Timestamp Converter →Steps
- 1Collect suspect timestamps from logs, tokens, or API responses.
- 2Determine whether values are seconds or milliseconds.
- 3Convert to readable dates and compare with expected business time.
- 4Validate timezone handling before changing backend logic.
Examples
- Explaining token-expiry mismatches caused by ms/sec confusion.
- Verifying scheduled job drift across regions.
What to avoid
- Comparing local time to UTC values without normalization.
- Treating millisecond values as seconds and misreading dates.
- Debugging expiry logic without checking clock skew.

FAQ
Seconds or milliseconds first?
Confirm unit first; incorrect unit causes the largest timestamp errors.
Can timezone alone break scheduling logic?
Yes, especially around daylight-saving transitions and mixed UTC/local assumptions.
