How can i get the System Time from the other host

I want to get the System Time from the other host in the LAN,How can I get the Time using Java.
Such as I am in WIN 2000 and I have a Unix host in LAN, I want to get unix host System time, How can I do it.

Open a socket to port 13 and read a string with the time.
-or-
Open a socket to port 27 and read 4 bytes that are a network order timestamp
Assuming that your UNIX machine has those services running, most do

Current time in the x-Axis

Hi everyone,
I have some problems putting a waveform together that shows the current time in the x-Axis.
I tried to do it with “timestamp” and “build waveform” but it didn’t work out. All I need is some values over the current time x-Axis.
All it shows in my waveform is the time since 1904, like it always does!
Probably a silly question, but can anyone help me out, maybe with an example VI?
TNX

Did you also set dt?
If I set some y-values, dt = 1 and x0 to current time, I get different times on the x-axis.
I attach a screenshot, that shows this.

Changing the System time in the JVM where Weblogic runs

Hi,
I am trying to change the System time where the Web-logic server (11g) runs using Mocking. I use "jmockit.jar" to mock the System.class. A Spring bean is created and through that I try to change the System time. I need to change the time for testing scenarios. For example, I need to backdate and do the testing for some scenarios. For the moment I do this manually and I want to automate this by changing only the time in the JVM where the application server runs. When I try to automate this using the Spring bean, I get an error as follows. Do anyone have any idea about this.

Hi,
I could manage to change the time in JVM where the Weblogic server runs. I loaded an Spring bean from my Test class and from that bean I set an offset (to shift the time) in the Mock class (say, MockSystem class). In this case I used the jmockit implementation for instrumentation purposes. The MockSystem class should not be instantiated by us and jmockit takes care of that part. What I had to do was defining the javaagent and another parameter ("-Djmockit-mocks=com.abc.common.service.impl.MockSystem") in the Weblogic server build XML (mentioned in the following URL[1]). But to work this the MockSystem.class file should be wrapped in a JAR file and included in Weblogic server/lib directory and define it in the Weblogic build XML file as a classpath. For more explanations visit this URL [2].

Displaying system time in the stage

I want to use the "put the time" function to display my
system time on the stage. Can someone help?

There are a few more formatting options using straight lingo.
Instead
of using "the time", you can use "the long time" which will
show the
hours, minutes, and seconds. Be careful though, since most of
Director's built in ways of getting the time/date can vary
depending on
the user's Operating System and preferences in the control
panel. For
instance, some may have 24 hour time and some may have AM/PM.
It is
dependent upon the user's OS.
BuddyAPI has a more configurable and controllable method, as
Applied CD
pointed out. That would be the best way probably.

How do you return System Time of the local box in FTP command

How do you return System Time of the local box in FTP command... since I want to output the system time of my local box copying to the FTP server...

Its asking me to enter a new date... I actually want to return it into a log file since I am using ws_ftp.... but the log files dont have any date time being returned... i just want to be able to echo that date time into the log file... but it doesnt do that... I also tried
SHELL ECHO %DATE% %TIME%
but it returns this in the log file
Processing Line 10 [SHELL ECHO %DATE% %TIME]
I also tried in my ws_ftp script and it says:
Processing Line 15 [!Date]
Sending command [!Date] with parameter []
!Date
500 '!DATE': command not understood
Failure in command [!Date]

How to pass Current System time in the target field?

Hi Experts
kindly help me in mapping a field in which I have to map current system time.
I think there is no standard function for time like the date so do i write a UDF for the same or any other way an in case a UDF than please help in that.
Thanks

Mathur no need to write UDF for that..
Use standard function Current date-------> In that (Target Format) u have to specify the time i.e: HHmmss
Thats it..... Noe use this function as u like...

How to set the system time in the program

Hi All,
How do we update the system time inside java programme.

AFAIK there is no easy (pure java) way: either you exec something (depending on your paltform) or use native code. Appropriate privileges will be necessary.

Get the target system time in the message mapping

Hi there,
I need to use the system time of target R/3 system in the message mapping. Any ideas how can I handle this?
Thanks,
Igor.

Thanks for your quick replies.
XI and R/3 system is in the same timezone but this is not relevant. I know it might sound strange but there is a reason I need to use time in the message mapping which is 2 minutes later than in the target system:
e.g. target system time: 16:58:32 I need to use 16:56:32 value in the mapping.
I found RFC MSS_GET_SY_DATE_TIME which can proide me with the value, just wondering if there is no other way how to do that other than RFC lookup ...
Thanks,
Igor

Howto Current System Time in the format YYYYMMDDHHMMSS

Hi, Is there a way to calculate current system time in java so the output will be in the format YYYYMMDDHHMMSS?

Create a Date object from the system time:
long now = System.currentTimeMillis();
java.util.Date date = new java.util.Date(now);
System.out.println(date);
You can then use the SimpleDateFormat class to format the Date however you want.

Current time for the X-axis in the wave chart

I understand that the "attribute node" function is edited to show the current year/month/day/hour/minute/sec in my waveform chart. However, the default year is 1904 and trying the "attribute node" still fails. Please anyone show me the step-by-step procedure to do it.
- An awl trying to learn L/V.

My L/V is Ver.5.0. Referencing your suggestion, on the panel I click X-scale -->, Formatting --> X- Scale Formatting. Then I arrive at "Scaling Factors". Here I see year "1904" and modification is impossible. I can not find any place to put value 7 as you suggested. Your suggestion to use ENUMS does not seem to be clear to impliment. Trying "Attribute Node" in the Diagram leads me to "X scale info", but further try does not make it. And I can not find "Offset and Multiplier" and "Get Date/Time" as you showed. Sorry to say that still I am not successful. This might be due to the version differences.
As a reference, I here attach the panel and diagram of my work.

Graph / Chart show system time in X-Axis.

I try to plot the temperature graph/ chart with respect to my system time. The problem is that the if i select the relative time it starts from 00:00 and if i select absolute time it always starts from 05:00 in 24Hrs.
I need X-Axis Chart/Graph show my system time and in Y- Axis it show the Temperature value which is received from serial port.

First I am very thankful to you for your kind cooperation. As I am beginner
my questions may be the unintelligent.
I have tried it and now the system time shows in graph. I have also a time
sync problem. After initializing graph with the time being the value of time
does not match with system time. Some time it is faster with respect
to system clock and some time it is slower with respect to system clock. I
observed it is slow when the data of graph is 1 byte long and when the data is
2 or 3 bytes long it goes fast.
The another problem is the chart Y-Axis Interpret HEX value (00 to FF) means 0-255
points only. My data is ASCII string with 4 characters like ‘9562’. Every character
will show the weightage as shown in attached file. I want to use the same ASCII
string to the input of graph for single point. Instead of HEX value (00 to FF).
And the another help from your side can you send me the book name or softcopy of LAB
View tutorial (Easy understandable).
Regards,
Azhar

How do i plot with the operating system time in one plot and show lines between cursors in another using the same XY graph?

I am having some trouble graphing two plots at once. One plot is to show the current temperature inside a chamber as a function of time. I am trying to pick the current time and temperature each second and plot it with each point being connected by a line. I am able to show a moving, blinking dot each second but I can't figure out how to develop an actual line with these dots. To make matters worse, the blinking dot is back in the year 1903. I understand that it uses seconds elapsed since 1903, and am trying to find out how to graph the current temperature with the system time.
The second plot is just 5 moveable cursors that are to be connected by a line. I am able to move the cursors and retrieve the position information, but I can't make a line between them.
I have attached my main .vi, though you may have to pick the graphing part off to have it work for you.

Main Module Chamber Testing I_O every 30 sec.vi ‏288 KB

You're not creating the XY graph data correctly. I've attached an example with a couple of simple XY Graphs. One is using a couple of shift registers to hold the spearate x and y arrays. I think this is what you were trying to do. The other one uses a VI from the shipping examples called XY Chart. It makes an XY Grpah act like a chart. I've also shown the correct way to display current time.Message Edited by Dennis Knutson on 05-12-2005 03:51 PM

How to insert the sysdate time into the database

hi all,
when i execute the following query,
insert into table_name
(date_field)
values
(to_date(sysdate, 'yyyy/mm/dd hh24:mi:ss'));
The value is inserted as 08-02-12 12:00:00. In this query, it always stores the default time as 12 a.m.
But i need to insert the original system time not the default one.
please help me how to rectify it.

I do not understand as to why you are using the to_date function on sysdate since sysdate is already in date format.
If date_field is of the data type date, then the following dml should work.
insert into table_name(date_field) values (sysdate);
In case date_field is a varchar2 field and you want to store the date and time in a string format, then the following statement should work.
insert into table_name (date_field)
values (to_char(sysdate, 'yyyy/mm/dd hh24:mi:ss'));

How to create a type of 'alarm event' based on acquired sensor data and system time?

Hello all,
I'm fairly new to LabVIEW and have successfully created a VI that reads voltage data from sensors. Each sensor outputs 2 voltage values and I treat these values as 2 different DBL values. I'd like to be able to record each voltage value as a base and then compare the subsequent data readings with that base. Once the base is determined, I'd like a sort of 'variable' set as "TIME" to be recorded at the moment the base voltage is recorded.
The alarm should occur (or anything Boolean set to TRUE I guess) once the continuously read voltage remains within certain limits for about 2 hours. I know I can compare the system time w/ the "TIME" that the voltage base value was recorded. If the voltage readings escape those limits, I'd like the voltage base value reset and the TIME set to the corresponding system time again.
I apologize in advance if this I haven't' described my problem well, but if anyone could help me figure out the best way to create this code, I would appreciate it much!
Thanks!
Solved!
Go to Solution.

ill try to illustrate a couple scenarios:
keep in mind that i dont necessarily want the voltages in these specific ranges, but just a range of +/- 20 mV ... in an above post i refer to a "base" voltage reading, in this case that would be 200 mV for V1 and 400 mV for V2, just because the voltage has shifted to those values for an extended amount of time each (> 2 seconds)
Scenario 1
1:00 pm
Sensor readings
Voltage 1: 200 mV
Voltage 2: 400 mV
between 1:00 and 3:00 pm:
Voltage 1 does not deviate from 180-220 mV range
Voltage 2 does not deviate from 380-420 mV range
at 3:00pm I want an alert/alarm/Boolean to change to 'true'
Scenario 2
1:00 pm
Sensor readings
Voltage 1: 200 mV
Voltage 2: 400 mV
at 1:45 pm:
Voltage 1: 2 mV
Voltage 2: 600 mV
Since the voltage has shifted out of the range, i want the new base voltage to equal whatever it changed to out of the range, and also the time spent within the new range (2 +/- 20 mV and 600 +/- 20 mV, respectively for V1 and V2) would be reset, so a new 2-hour counter would begin
