In web server logs, timestamps are typically recorded using which standard to ensure consistent correlation across servers?

• A. UTC
• B. GMT
• C. TAI
• D. UT

Answer: (A)

Using a universal time standard is essential for correlating events across servers. Coordinated Universal Time (UTC) serves as this global reference because it does not depend on local time zones or daylight saving changes. That means the same moment is recorded identically no matter where the server is located, making cross-server log analysis reliable. Other options either refer to time zones or are older/less precise time scales not designed for everyday logging, so they don’t provide the consistent baseline that UTC offers.
