    Subject[PATCH 4.19 292/639] rtc: Fix timestamp value for RTC_TIMESTAMP_BEGIN_1900
    Date
    From: Geert Uytterhoeven <geert+renesas@glider.be>

    [ Upstream commit d3062d1d7415cb5a37777220357aca51a491c3d7 ]

    Printing "mktime64(1900, 1, 1, 0, 0, 0)" gives -2208988800.

    Fixes: 83bbc5ac63326433 ("rtc: Add useful timestamp definitions")
