Seconds since 1970

MESYETI

I know about:

(days since 2000)

this is a very useful feature, but computers use seconds since 1970..not days since 2000
So can

(seconds since 1970)

be added? It will be even more useful!

Could you please give some examples on how this could be used? I don't see how it would be useful.

Not many use the days since 2000 block anyways, so no support as this isn't that useful.

(((days since 2000) - (10957.2657)) * (31556925.216)

It can be used for scratch virtual machines, for example, you'll need some way to have the computer know the date and time.. So seconds since 1970 is very good for this purpose! ALL computers have it!

Sorry, but days since 2000 doesn't update every second, so that won't work..

That can't tell time

It has twelve digits of precision.
Not only can it tell time, but better than any other block in Scratch.

It doesn't update every second, and 1970 is a better time..

It does update every second: it returns the amount of days with decimals. And also, 1970 is subjectively a better time, because to me it actually represents nothing.

Yes, I've seen it in decimals. I've seen it not update every second

Let me try again..

Okay, put the days since 2000 block inside a variable block (stack type, not circle). Put it inside a forever loop, show the variable, and run the script. It updates every second.

I shared a project showing that it does not update every second

Do you want your block to update EXACTLY every second?

Yes

Yes

If you mean that it takes more that 1 second to update, it's because the “say” block rounds up decimal numbers. If you click the “days since 2000” in the editor, you'll see that it takes even less than 1 second to update.

There is a block that can detect seconds in the sensing section:

(current [second v])

Also you can just estimate that it's been 1,576,800,000 seconds since 1970.

No, I don't like current seconds

And yes, I have found that days since 2000 updates less than every second.. Sorry for bothering you..

SpideyPlaysMC

No it's fine.
