NET \\computer /SET or NET /DOMAIN:domain /SET to synchronize the local computer's time with a remote computer or domain controller.NET HELP TIME for more time synchronization options.DATE and TIME originally were only meant to adjust the date and time after each cold boot of the first generations of PC's, since these old PC's were not equipped with batteries to keep the internal clock going.
NT and OS/2 provide ways to show only the current date or time, without asking you to adjust it.
In NT, TIME /T and DATE /T will display only the current time and date, respectively.
In OS/2 DOS sessions, TIME /N and DATE /N will do the same, though preceded by a statement that the current time/date is set to the values displayed.
In real DOS there's only the hard way to display date and time:
@ECHO OFF VER | TIME > TEMP.BAT ECHO SET TIME=%%3>CURRENT.BAT CALL TEMP.BAT DEL TEMP.BAT DEL CURRENT.BAT ECHO It's %TIME% now
This batch file, as shown here, works only if your DOS version will say something like:
Current time is 5:08:14.47 PM
when executing the TIME command. If your DOS version isn't English you have to change the name of CURRENT.BAT and the number of the parameter (%%3)
Let's use a Dutch DOS version as an example.
VER | TIME will display:
Tijd is nu ingesteld op: 17:08:14.47
So now we'll have to use TIJD.BAT instead of CURRENT.BAT, and %%3 must be changed to %%5 because now, instead of:
Current time is 5:08:14.47 PM
TEMP.BAT will contain a line:
Tijd is nu ingesteld op: 17:08:14.47
Now the third line of our batch file should be:
ECHO SET TIME=%%5>TIJD.BAT
and the sixth line:
DEL TIJD.BAT
The above batch file can be made multi-lingual.
The price we pay is more code and more temporary batch files to create and clean up:
@ECHO OFF REM Temporary batch file common to all DOS versions VER | TIME > TEMP.BAT REM Temporary batch file for English DOS version ECHO SET TIME=%%3>CURRENT.BAT REM Temporary batch file for Dutch DOS version ECHO SET TIME=%%5>TIJD.BAT CALL TEMP.BAT DEL TEMP.BAT DEL CURRENT.BAT DEL TIJD.BAT ECHO It's %TIME% now
| Note: | An added complication is the use of 12 hour AM/PM vs. 24 hour notation. 6:00 PM is 18:00 so we would need to add 12 hours. In most cases that won't be necessary, as you can append the AM or PM to the variable using SET TIME=%%3%%4>CURRENT.BAT |
These batch files set the variable TIME to the time they are executed.
The same tricks work for DATE as well, you only need to make some minor adjustments.

The PROMPT command has some useful options, like $D and $T, that allow us to store the week day, current date and current time in environment variables, independent of the operating system's language!
The resulting environment variable is language dependent, though.
So I added a routine to remove forward slashes (or any other FOR delimiter) from the DATE variable (which is then stored in the DATE2 variable), allowing the variable to be used in file names.
This technique to remove or replace forward slashes works in all DOS versions up to and including MS-DOS 6.22, PC-DOS 7 and OS/2 Warp 4's DOS box. It will not work in MS-DOS 7.*, which means the %DATE2% variable is useless in MS-DOS 7.*.
However, the %DATE% and %TIME% variables are valid in all DOS versions, including MS-DOS 7.*.
@ECHO OFF :: DateTime.bat :: Set environment variables with current Date, Time and DayOfWeek :: Recursion IF NOT "%3"=="" GOTO SecondTime :: Create temporary batch file > TEMPDTT1.BAT ECHO @PROMPT %0 $D $T :: Do _N_O_T_ replace "COMMAND /C" with CALL in the next line > TEMPDTT2.BAT COMMAND /C TEMPDTT1.BAT TEMPDTT2 :SecondTime DEL TEMPDTT?.BAT SET DOW=%1 SET DATE=%2 SET TIME=%3 :: Remove forward slashes from DATE variable and store result in DATE2 IF EXIST DATE2.BAT DEL DATE2.BAT SET DATE2= :: Parse DATE variable and create temporary batch :: file to recreate DATE without forward slashes >> DATE2.BAT FOR %%A IN (/%DATE%) DO ECHO SET DATE2=%%DATE2%%%%A CALL DATE2.BAT DEL DATE2.BAT

Check out BatchMan, by Michael Mefford, if you want an easy to use and language independent way to check the system time or date (and much more) in batch files.
