Description

Removes to_timestamp() and the module-level epoch constant from sentry_sdk/utils.py. Nothing uses either of them.

#4899 (removing the old metrics code) deleted the last three callers of to_timestamp, all in sentry_sdk/metrics.py, plus its import there. epoch was only ever used inside to_timestamp.

Evidence

• grep -rnw to_timestamp sentry_sdk tests scripts only matches the definition.
• grep -rnw epoch sentry_sdk tests only matches the definition and its use in to_timestamp. The other match is the (?P<epoch>...) regex group in the version parser, which isn't related.
• git log -S "to_timestamp(" -- sentry_sdk tests shows chore: Remove old metrics code #4899 as the last change to touch a call site.
• No open PR diff in this repo mentions to_timestamp or epoch.

Why it's safe

• sentry_sdk.utils is an internal module. Neither name is re-exported from sentry_sdk or listed in docs/, and neither appears in CHANGELOG.md or MIGRATION_GUIDE.md.
• The helper had a latent bug: it subtracted from a naive datetime(1970, 1, 1), so passing it a timezone-aware datetime (the SDK uses aware UTC datetimes everywhere) raised TypeError. Leaving it around invites someone to reuse it by mistake.
• datetime is still imported and used elsewhere in the module.
• No runtime behavior changes.

Checks

• uv run ruff check sentry_sdk tests and ruff format --check pass.
• uv run --group typing mypy sentry_sdk passes with no issues.
• TESTPATH="tests/test_utils.py tests/test_basics.py tests/test_client.py" uv run tox -e py3.14-common: 587 passed, 3 skipped.

Issues

None. Found by a dead-code sweep.
