包路径：com.datastax.driver.core.LocalDate
类名称：LocalDate
方法名：fromMillisSinceEpoch

LocalDate.fromMillisSinceEpoch介绍

[英]Builds a new instance from a number of milliseconds since January 1st, 1970 GMT. Note that if the given number does not correspond to a whole number of days, it will be rounded towards 0.
[中]从1970年1月1日GMT以来的毫秒数生成一个新实例。请注意，如果给定的数字与天数不一致，它将四舍五入到0。
