Helper.timestampFromString介绍

[英]Answer a Timestamp from a string representation. This method will accept strings in the following formats: YYYY/MM/DD HH:MM:SS, YY/MM/DD HH:MM:SS, YYYY-MM-DD HH:MM:SS, YY-MM-DD HH:MM:SS
[中]从字符串表示中回答时间戳。此方法将接受以下格式的字符串：YYYY/MM/DD HH:MM:SS、YY/MM/DD HH:MM:SS、YYYY-MM-DD HH:MM:SS、YY-MM-DD HH:MM:SS
