While the RTC framework intends to only handle dates after 1970 for consumers, time conversion must also work for earlier dates to cover e.g. storing dates beyond an RTC's range_max. This is most relevant for the rtc-mt6397 driver that has range_min = RTC_TIMESTAMP_BEGIN_1900; range_max = mktime64(2027, 12, 31, 23, 59, 59); and so needs working support for timestamps in 1900 starting in less than three years. So shift the tested interval of timestamps to also cover years 1900 to 1970.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
