Showing only current date in the data form webpart

When i try to put one of my date formatted fields in the page, without notice to it's real value, only current date have been shown.

it's happen in only one of my pages and after delete it and redesign it, every thing goes OK. it's second time i got this problem and previous occur is on other server and table. my code is simple and standard:

<xsl:value-of select="@ADate"/>
