Date and Time Issue in CF7

Hi all,

I'm using CF7 and having a weird problem with date and time.

I have a loop just display a date and time: DateFormat(now(), 'mm/dd/yyyy') & " " & TimeFormat(now(), 'h:mm:ss tt');

But sometimes, the time is incorrect as following

249752000 02 Days, 21 Hours, 22 Minutes, 32 Second(s). Tue Apr 15 2008 17:37:28 GMT+0700 (SE Asia Standard Time)

Why the time is "Tue Apr 15 2008 17:37:32 GMT+0700 (SE Asia Standard Time)" and then jump to "Tue Apr 15 2008 17:38:43 GMT+0700 (SE Asia Standard Time)" only after 1 second? It doesn't often happen, just sometimes. Do you know why? Please help me. Thanks very much.
