Timezone data should always be the actual timezone, not the offset. Offsets don't take into account the political nature of time. For example, in Europe in 2021

Timezone data should always be the actual timezone, not the offset. Offsets don't take into account the political nature of time. For example, in Europe in 2021, countries will cease to use daylight savings, changing their time offsets permanently.
