```Beata:

You are correct that
AbsoluteTime["20100520"]
Works
In[1]:= AbsoluteTime["20100520"]
Out[1]= 3483302400

Your list c is a list of numbers. When you try the single value, you enclose
it in quotes.
Here are 2 list one is a list of strings d, c is your version.

d={"20100520","20100519","20100512","20100516","20100430","200100425","20100411","20100407"};
c={20100520,20100519,20100512,20100516,20100430,200100425,20100411,20100407};

In[3]:= Map[AbsoluteTime,d, 1]
Out[3]=
{3483302400,3483216000,3482611200,3482956800,3481574400,6314499548755200,3479932800,3479587200}

In[4]:= Map[AbsoluteTime,c, 1]
Out[4]=
{1.3359792985435000*10^9,1.3359792985435000*10^9,1.3359792985435000*10^9,1.3359792985435000*10^9,1.3359792985435000*10^9,1.3359792985435000*10^9,1.3359792985435000*10^9,1.3359792985435000*10^9}

In[5]:= Map[AbsoluteTime, Map[ToString,c,1],1]
Out[5]=
{3483302400,3483216000,3482611200,3482956800,3481574400,6314499548755200,3479932800,3479587200}

If you wish to leave your list as a list of integers the see above.

So you need to
