Thanks for the PR. I'll take a look on Wednesday when I'm back at work |

Pull request overview
Fixes incorrect UTC offset calculation during DST so timestamps (notably session_start_time) are written with the correct timezone offset and don’t appear to be in the future (per nwbinspector’s check_session_start_time_future_date).
Changes:
- Update
get_utc_offset_secondsto use platform-specific, DST-aware mechanisms (tm_gmtoffon Unix/macOS;_get_timezone+_get_dstbiason Windows; adjusted fallback). - Add a unit test ensuring
get_utc_offset_secondsmatches the OS-reported offset (including DST). - Add an integration-style test ensuring the written
session_start_timeis not in the future once converted to UTC.

src/Utils.hpp |
Reworks UTC offset computation to be DST-correct using platform-specific approaches and an improved fallback. |
tests/testUtilsFunctions.cpp |
Adds a unit test asserting the computed UTC offset matches OS-provided offset values (DST-inclusive). |
tests/testNWBFile.cpp |
Adds a test that parses session_start_time, converts it to UTC, and asserts it is not in the future. |

std::sscanf is used here, but this file doesn’t include <cstdio>, which can cause build failures on some toolchains (e.g., std::sscanf not declared / not in std). Add the proper header (or avoid the std::-qualified overload and include the right C header) to make this compilation unit self-contained.

The return value of std::sscanf is ignored. If parsing fails (unexpected format, locale differences, etc.), parsed/offset fields may remain default/partial and the computed epoch becomes meaningless (potentially making the test flaky). Capture the conversion count and REQUIRE it matches the expected number of assignments before using the parsed values.

@cboulay could please address the two issues identified by copilot related to the use of std::sscanf (i.e., add the missing include for <cstdio> and a REQUIRE statement to check the return value of std::sscanf. Also, could you please add an entry in CHANGELOG.md to describe the fix from this PR.
Fixes #294
