Batch: Timestamp to UNIX Time

Question

For all I know, Batch does not have a command that gives the UNIX time. The closest one I can find is %time%, which only displays the timestamp.

Is ther

Answer 1

What about simple 1-line long C program returning UNIX timestamp? You can retrieve value from %errorlevel% in batch script.

#include 
#include 

int main(void)
{
    return (int) time(NULL);
}

In my test in command prompt it worked:

C:\Users\dabaran\Desktop\cs50\src\C>.\time || echo %errorlevel% && set mytstamp=%errorlevel%
1419609373

C:\Users\dabaran\Desktop\cs50\src\C>echo %mytstamp%
1419609373
