Questions answered in this file

Can I use today's time-zone offset for an old case?

Not safely without checking historical rules for the date and location. Offsets and observance can change.

Should all times be converted to UTC?

Only when the source basis is sufficiently known and normalization serves the task. Always preserve the original entry and conversion assumptions.

Why can a local time occur twice?

An autumn daylight-saving clock change can repeat an hour in observing jurisdictions. Additional context is needed to identify the occurrence.

Does a one-hour discrepancy prove dishonesty?

No. Investigate clock basis, daylight-saving rules, source precision, and recording delays before drawing conclusions.

What if the source gives no time zone?

Label the basis unknown or document a qualified inference. Do not publish a precise converted time as established fact.
