NAME
date - display or
set the date and time
SYNOPSIS
date [-u]
date [-u]
+format
date [-u]
[mmddhhmm[[cc]yy]]
date [-a
[-]sss[.fff]]
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.
-a
[-]sss[.fff]
Slowly adjust the time by sss.fff seconds (fff
represents
fractions of a second). This adjustment can be positive
or
negative. The system's clock will be sped up or slowed
down
until it has drifted by the number of seconds
specified.
Formats
The date command has two forms for displaying the date and time
and
one form for setting
them.
date
[-u]
Display the current date and time. The output is
the
same as for the %c formatting directive for all
languages
except the C default language. See Formatting
Directives
and EXAMPLES
below.
date
[-u]
+format
Display the current date and time according to
formatting
directives specified in format, which is a string of
zero
or more formatting directives and ordinary
characters.
If it contains blanks, enclose it in apostrophes
or
quotation marks.

date(1) date(1)
See Formatting Directives
below.
All ordinary characters are copied unchanged into
the
output
string.
The output string is always terminated with a
newline
character.
If + is specified and format is omitted, only a
newline
is output.
date [-u]
[mmddhhmm[[cc]yy]]
Set the HP-UX system clock to the date and
time
specified. You require the superuser
privilege.
If you include the -u option, the specified date and
time
is assumed to be in Coordinated Universal Time
(UTC).
The numeric argument is interpreted left to right
in
two-digit pairs as
follows:
mm Month number
[01-12].
dd Day number in the month
[01-31].
hh Hour number (24-hour system)
[00-23].
mm Minute number
[00-59].
cc Century minus one
[19-20].
yy Last two digits of the year number [70-99,
00-
37 (1970-1999, 2000-2037)]. If omitted,
the
current year is
used.
If you attempt to set the date backwards, date
generates
the
warning,
do you really want to run time
backwards?[yes/no]
Type yes or the equivalent for your locale to set
the
