man date:

date recognizes the following option:
-u Input and output values in Coordinated Universal Time (UTC), functionally equivalent to Greenwich Mean Time (GMT), instead of in local time.

man date:
-u Input and output values in Coordinated Universal Time (UTC), functionally equivalent to Greenwich Mean Time (GMT),
instead of in local time.

Your local time is 8 hours ahead of UTC (EAT-8). That makes the difference.

Here is part of the man page of date:

DESCRIPTION
The date command displays or sets the current HP-UX system clock date and time. Since the HP-UX system operates in Coordinated Universal Time (UTC), date automatically converts to and from local standard or daylight/summer time, based on your TZ environment variable. See Environment Variables in EXTERNAL INFLUENCES below.

Options
date recognizes the following option:

-u Input and output values in coordinated Universal Time (UTC), functionally equivalent to Greenwich Mean Time (GMT), instead of in local time.

Hope this helps.
Kenny.
