Timestamp problem

Ryan Ma — Wed, 12 Dec 2001 08:04:53 GMT

I am writing a program to convert timestamp back to date/time format.

But it fail to compile.

I think this is because I use the kernel compiler which has limit function.

So how can I do it in other way?

Thx.

If it depends on the compiler you should install a full ANSI compiler like gcc
Download it from :

Hi,

Can you use perl, e.g.:

# perl -e 'print scalar localtime($ARGV[0]),"\n"' 1008145059

Hi Ryan:

You can also do this:

# TS=1000000000
echo "0d${TS}=Y"|adb

Regards!

Hi Robin,

Why I produce no result?
I follow your command already.

# perl -e 'print scalar localtime($ARGV[0]),"\n"' 1008145059

Hi Ryan,

I guess you're running V4 of perl. The long-winded way for V4 would be to create a perl script:

@dow=("Sun","Mon","Tue","Wed","Thu","Fri","Sat");
@moy=("Jan","Feb","Mar","Apr","May","Jun","Jul","Aug","Sep","Oct","Nov","Dec");
($sec, $min, $hour, $day, $month, $year, $wday)=(localtime($ARGV[0]))[0,1,2,3,4,5,6];
printf ("%s %s %02d %02d:%02d:%02d %04d\n",$dow[$wday],$moy[$month],$day,$hour,$min,$sec,$year+1900);

then run:

# perl yourscript timestamp

Rgds, Robin
