Broken chronological order in Sharepoint ULS logs.

Hi,

I have SharePoint 2007 and Project Server 2007 installed.

My farm consists of two servers - app server and database server.

I've noticed strange thing in ULS logs - some entries in it are not in chronological order.

For example, first goes:

10/09/2012 11:56:53.57

and than

10/09/2012 11:56:53.49

Is this normal? If not then how can i fix it?

Best regards, Chernobrivets
