合格时间戳作为法庭证据：eIDAS 第 41 条下的欧盟法律指南（2026）
根据 eIDAS 第 41 条，合格电子时间戳享有准确性的法律推定，并在全部 27 个欧盟成员国可作为法庭证据采信。本指南阐释技术要求（RFC 3161 + ETSI EN 319 422）、瑞士法院如何处理等同的 ZertES 合格时间戳，以及法律顾问和知识产权管理者在欧盟和瑞士诉讼中出示时间戳证据所必须遵循的确切步骤。
2024年9月，法兰克福一家信托公司(Treuhand)被召作为商业纠纷中的中立文件保管人。其客户，一家中型制造集团，需要证明一份供应协议的签署日期，而对方声称该日期系倒填。该公司在其文件服务器上保存了一份PDF副本。服务器元数据可被修改，电子邮件时间戳不具备QTSP支持。在没有eIDAS第41条下的合格电子时间戳的情况下，该公司拥有书面证据但没有法律推定，举证责任在长达18个月的仲裁过程中完全落在客户身上。
是的。根据eIDAS条例第41条，合格电子时间戳就其所指示的日期和时间的准确性以及所涉数据的完整性享有法律推定。该推定在全部27个欧盟成员国无需进一步举证即可执行，将举证责任转移至对方当事人。
