This is not a problem for systems with time information extended to 64-bit, but it is a problem for programs developed on 32-bit systems that will continue to be used after 2038. The authors have proposed a low-cost method of modifying such programs so that they can be used after 2038 on 32-bit systems. In this paper, we propose a method for easily identifying the parts of an application that need to be modified when considering the conversion to 64-bit systems to completely solve the 2038 problem. We also report on problems found in the amd64 environment of FreeBSD 13.2-RELEASE using this method.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"8","bibliographic_titles":[{"bibliographic_title":"研究報告ソフトウェア工学（SE）"}],"bibliographicPageStart":"1","bibliographicIssueDates":{"bibliographicIssueDate":"2023-11-23","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"4","bibliographicVolumeNumber":"2023-SE-215"}]},"relation_version_is_last":true,"weko_creator_id":"44499"},"id":230480,"links":{}}
