Example
    <h3>DateConvert Example</h3>
    <!--- This shows conversion of current date - time to UTC and back. --->
    <cfset curDate = Now()>
    <p><cfoutput>The current date and time: #curDate#. </cfoutput></p>
    <cfset utcDate = DateConvert("local2utc", curDate)>
    <cfoutput>
       <p>The current date and time converted to UTC time: #utcDate#.</p>
    </cfoutput>
    <!--- This code checks whether form was submitted. If so, the code generates
    the CFML date with the CreateDateTime function. --->
    <cfif IsDefined("FORM.submit")>
       <cfset yourDate = CreateDateTime(FORM.year, FORM.month, FORM.day,
    FORM.hour,FORM.minute, FORM.second)>
       <p><cfoutput>Your date value, presented as a ColdFusion date/time
    string:#yourdate#.</cfoutput></p>
      <cfset yourUTC = DateConvert("local2utc", yourDate)>
       <p><cfoutput>Your date and time value, converted to Coordinated Universal
    Time
    (UTC): #yourUTC#.</cfoutput></p>
       <p><cfoutput>Your UTC date and time, converted back to local date and time:
    #DateConvert("utc2local", yourUTC)#.
    </cfoutput></p>
    <cfelse>
       Type the date and time, and press Enter to see the conversion.
