### What changes were proposed in this pull request? This PR aims to create the timezone string offset before `startTimestamp` in `ArrowWriterHelper.toFBType`. This is the same fix as upstream `apache/arrow-swift`. - https://github.com/apache/arrow-swift/pull/148 (2026-03-25) ### Why are the changes needed? FlatBuffers requires strings to be created before starting the table that references them. Otherwise, debug builds crash in `createDataFrame` with `TIMESTAMP` columns. ``` $ swift test --no-parallel --filter "CreateDataFrameTests/supportedTypes" ... FlatBuffers/FlatBufferBuilder.swift:339: Assertion failed: Object serialization must not be nested ``` Release builds are not affected because `assert` is disabled there. ### Does this PR introduce _any_ user-facing change? No behavior change in release builds. ### How was this patch tested? Pass the CIs and manually run `CreateDataFrameTests` with a debug build. ### Was this patch authored or co-authored using generative AI tooling?
