The Munich ChronoType Questionnaire (MCTQ) has now been available for more than 15 years and its original publication has been cited 1240 times (Google Scholar, May 2019). Additionally, its online version, which was available until July 2017, produced almost 300,000 entries from all over the world (MCTQ database). The MCTQ has gone through several versions, has been translated into 13 languages, and has been validated against other more objective measures of daily timing in several independent studies. Besides being used as a method to correlate circadian features of human biology with other factors-ranging from health issues to geographical factors-the MCTQ gave rise to the quantification of old wisdoms, like "teenagers are late", and has produced new concepts, like social jetlag. Some like the MCTQ's simplicity and some view it critically. Therefore, it is time to present a self-critical view on the MCTQ, to address some misunderstandings, and give some definitions of the MCTQ-derived chronotype and the concept of social jetlag.
慕尼黑时间类型问卷（MCTQ）现已问世超过15年，其原始出版物已被引用1240次（谷歌学术，2019年5月）。此外，其在线版本一直开放到2017年7月，来自世界各地的条目近30万条（MCTQ数据库）。MCTQ已经历了几个版本，被翻译成13种语言，并在多项独立研究中与其他更客观的日常时间测量方法进行了验证。除了作为一种将人类生物学的昼夜节律特征与从健康问题到地理因素等其他因素相关联的方法外，MCTQ还对诸如“青少年晚睡”等古老智慧进行了量化，并产生了诸如社会时差等新概念。有些人喜欢MCTQ的简单性，有些人则对其持批评态度。因此，现在是时候对MCTQ进行自我批评，解决一些误解，并给出一些关于MCTQ衍生的时间类型和社会时差概念的定义了。
