  • 1.  How to make vgda timestamp human readable

    Hello.

    Searching for clvgdats returns no hits so it is very probable that this topic has not been seen here.

    Does anybody know how to interpret the output of clvgdats?

    For example, what is 47ab38f737e0acd6.

    It is obviously not seconds since epoch.
    It looks hexadecimal but neither does BCD make sense (digits greater than 9) nor does converting the hex codes to characters (G«8÷7à¬Ö).

    Thanks.

    Just a guess, take the first 8 digits as the seconds from epoch, you know how unix loves to pin things down to a billionth of a second.

    This gives 38.127967243784880771182141045155 years!

    I'll let you do the rest of the maths to see if it works.

    1. you have "47ab38f737e0acd6"
    2. take first 8 and you get "47AB38F"
    3. convert this:
    # perl -e 'my $t=localtime 0x47AB38F; print $t . "\n"'
    4. and you get Fri May 19 21:03:43 1972

    Did you mean:

    1. you have "47ab38f737e0acd6"
    2. take first 8 and you get "47AB38F7"
    3. convert this:
    1. perl -e 'my $t=localtime 0x47AB38F7; print $t . "\n"'

    ????

    Result (date/time) is much better if you really take first 8 and not only 7 as I did it by mistake. Thx for correction.

    perl -e 'my $t=localtime 0x47AB38F7; print $t . "\n"'

    Why not just use the readvgda command which gives you all the data you may need about the vgda in human readable format ?
