What is UTC and why is it used for servers?

UTC (Coordinated Universal Time) is the global time standard — it has no timezone offset and does not observe daylight saving time. Servers log in UTC to avoid ambiguity during DST transitions and make log correlation across regions reliable.

What is the difference between UTC and GMT?

UTC and GMT are practically equivalent for everyday use — both have 0 offset from the prime meridian. UTC is the modern standard maintained by atomic clocks, while GMT is a historical timezone. Technically, UTC is more precise.

How does daylight saving time affect timezone conversion?

DST shifts clocks forward in spring and back in autumn in many regions. The offset between two time zones can change by 1 hour when one observes DST and the other doesn't (or observes it on different dates). Always use IANA timezone names (America/New_York, not EST) for correct DST handling.
