Hamburg operates on Europe/Berlin, abbreviated as GMT+1, which is currently UTC+01:00 from Coordinated Universal Time. The IANA Time Zone Database (also known as the tz database or zoneinfo) records this under the identifier Europe/Berlin. That identifier is what your phone, laptop, and every major web service uses when they display a localized time for Hamburg.
The designation Europe/Berlin follows the IANA convention of naming zones after the largest city in that timezone region. This naming is geographic, not political, it reflects where the zone is observed, not which government controls it. The full record for this zone, including historical UTC offsets and past DST rule changes, is publicly available in the Wikipedia list of tz database time zones.
