- Replace time_t with int64_t for explicit 64-bit timestamp handling - Replace localtime() with thread-safe localtime_r() - Add <cstdint> header for int64_t type support Co-Authored-By: Arthur Poon <arthur.poon@windsurf.com>

- Use time_t instead of int64_t to match localtime_r signature - On 64-bit systems, time_t is already 64-bit and Y2038-safe - Keep using thread-safe localtime_r instead of localtime Co-Authored-By: Arthur Poon <arthur.poon@windsurf.com>

Why I did it
Fix potential Y2038 timestamp overflow issue in the rsyslog plugin's timestamp formatter. The original code used
localtime()which is not thread-safe as it uses a static buffer. On 64-bit systems,time_tis already 64-bit and Y2038-safe.Work item tracking
How I did it
localtime()with thread-safelocaltime_r()time_tis already 64-bit on 64-bit systemsHow to verify it
Which release branch to backport (provide reason below if selected)
Tested branch (Please provide the tested image version)
Description for the changelog
Improve thread safety in rsyslog plugin timestamp formatter by using localtime_r

Updates since last revision:
time_tdirectly instead ofint64_t(which caused type mismatch withlocaltime_r())<cstdint>headerHuman Review Checklist:
time_tis already 64-bitlocaltime_r()usage is correct (passestime_t*andstruct tm*)Requested by: Arthur Poon (@arthurkkp-cog)
