Java Applet (that can also be run as an application).

----

Notes:

You must install the Java JRE to use this program.
See http://mindprod.com/jgloss/jgloss/jre.html

This hybrid program is mainly designed to be used as an Applet in a
browser but is can also be used from the command prompt, e.g. under
Windows command.exe or JPSoft tcc.exe, formerly called the DOS box. Just
clicking the programs in a directory listing will not do anything useful.  
Just typing the program names at the command prompt will not either.

This program requires a manual install! See below.

I put out an avalanche of free software into the world, and submit PAD
files to hundreds of distribution sites, but I rarely hear back from
anyone.  What's happening?  Does it all just work fine?  It is so
complicated nobody can figure out how to use it and they give up on it?
It is it useful?  Since everyone has the source, do people just fix the
programs to their liking themselves?  Did you have trouble installing?  Do
I presume you know too much?  I would be happy to hear from you about your
experiences, positive or negative and your requests for improvements.  A
one-line email to roedy@mindprod.com would be great.

===> Free <===
Full source included.
You may even include the source code, modified or unmodified
in free/commercial open source/proprietary programs that you write and distribute.
May be used freely for any purpose but military.
For more details on this restriction, see
http://mindprod.com/contact/nonmil.html
If you include any Canadian Mind Products code in your own applications,
your app too must be labelled non-military use only.

All Java jars and source code are included. If you need the class files or Javadoc, you will have to build them yourself. To streamline the zip downloads, class files and Javadoc have been removed.

Prerequisites:

This program runs under any OS that supports Java,
(e.g.W2K/XP/W2003/Vista/W2008/W7-32/W7-64/W8-32/W8-64/Linux/LinuxARM/LinuxX86
/LinuxX64/Ubuntu/Solaris/SolarisSPARC/SolarisSPARC64/SolarisX86/SolarisX64/OSX/AIX...)
so long as you have
<><> Java version 1.8 <><> or later installed (32-bit or 64-bit Java).
See http://mindprod.com/jgloss/installingjava.html for details.

----

Installing on a PC:

Download source and compiled jar files to run on your own machine as an application or Applet
First install a recent Java JDK or JVM.
See http://mindprod.com/jgloss/installingjava.html.
To install, extract the zip download with WinZip
(or similar unzip utility) into any directory you please,
often J:\ --  ticking off the <span class="click">use folder names</span> option.
To run as an application, type:
java.exe %JAVA_OPTIONS -ea -jar J:\com\mindprod\snaptime\snaptime.jar {put any parms here}

adjusting as necessary to account for where the jar file is.

----

Installing on a MacIntosh:

Use Safari to download source and compiled jar files to run on your own machine as an application or Applet.
Safari will automatically unpack the zip into ~/Downloads (version 10.5)
[or on the Desktop (version 10.4 and earlier)].
First install a recent Java JDK or JVM.
See http://mindprod.com/jgloss/installingjava.html.
You may optionally move the download tree to a permanent home.
I don't have a MacIntosh, just a PC, so I can't test my Java programs for Mac compatibility.
In theory they should work without problems, but in practice that does not always happen.
If you have problems please, let me know, preferably with screenshots and complete verbatim error messages.
To run as an application, without parameters, just double click the jar file.

To run as an application with parameters, in bash shell type:
open Terminal.app
cd ~/Desktop
java.exe -ea -jar com/mindprod/snaptime/snaptime.jar {put any parms here}

adjusting as necessary to account for where the jar file is.

----

Rebuilding:

The zip already contains the necessary jar files, so unless you modify
the program, there is no need to recompile the source or rebuild the jar.
Configure.java basedir="E:/" in rebuild.xml to the drive where your files are.
Use ANT and rebuild.xml, not build.xml, to recompile and recreate the jar.

----

Use:

SnapTime is similar to a stop watch. The difference is, it works in absolute time.
Every time you click the SNAP button, it captures the current time and displays
it in a list. A traditional computer stop watch captures the number of seconds
since you started timing.
What is it for? After I complained about the daily time signal being late, the
National Research Council asked me to measure how delayed the CBC radio time
signal is each day by the time it gets to Victoria. I wrote SnapTime to solve
that problem, at least approximately. I can click SNAP when I hear the tone,
and then can see how many milliseconds after 10 AM it is.
I was also curious about how in sync my NTP computer clock is with my
radio-synched watch. I can use it for that too.
If you can think of other uses for it, please let me know.
