Simple English translation:
Title: Why can't 1920 be set as the current date in Date and time settings?

Question:
Hello!

I read this news article (link to said article).

Why can't a year earlier than 1970 (such as 1920) be selected under Date and time settings?

The earliest selectable date is 1.1.1970.

Thank you @jollailija for your translation :)

I'm more curios why there is a choice til 1920 year(in GUI), if only 1970 year and later can be used in settings?

What happens when you select it? You get an error, or nothing happen?

Okay, I misunderstood your question. Maybe Jolla supports negative timestamps so you can set your birthdays?

iOS (as well as all Linuxes) use a thing called Unix time (look it up on Wikipedia). It works by counting the seconds that have passed since 00:00 (UTC) 1.1.1970. This way every system can have the same time in an easy format (a natural number) without timezone or cultural issues.

The current time as I write this is about 1455224300 (seconds since the start of 1970)

Could you also provide the translation of the question please? (since you seem to have understood it :) )

Okay, I'll post it as comment on the question as I am not sure.

well in sailfish you can set date manually and it starts with 1920. so i think question was, why is it possible in sailfish to select a pre 1970 date when unix date starts with 1970
