Wayne:
Thanks for your help...I got my time stamper to read the "timestamp" text file (ex. T_174359.bmp 60) and stamp time points on stack slices...but it has an odd bug.
1. When I run this macro the first time..no time points appear on the slices in the stack.
2. It only prints out time points like 9:56 on the stack slices, when I use the "text tool" to draw text on a stack slice.
3. Then running the macro is fine and the time label metadata appear on all the stack slices.
4. Have I missed something?
Ethan.
// "Label series using time stamps in DateLog.txt in local director
requires("1.43");
print("\\Clear"); //empties the Log
dir = getDirectory("Choose a Directory ");//sets path = dir
list = File.openAsString(dir+"Timelog.txt"); // opens file
entries = split(list, "\n"); // splits into lines of text
n = entries.length;// line length value of Timelog.txt
run("Colors...", "foreground=white background=black selection=white");
selectWindow("stack"); //select Log-window
for (i=1; i<=n; i++) {
setSlice(i); // select slice number
items = split(entries[i-1]);
j = parseInt(items[1]);
// floor - largest value of j under 60 that is an integer
s = ""+pad(floor((j/60)%60))+":"+pad(j%60); // time sec/60 stuff
setMetadata("Label", s);
}
selectWindow("stack"); //select Log-window
setTool("text");
run("Label...", "format=Label x=20 y=200 font=32 use");
function pad(n) {
str = toString(n); // decimal rep of number j
if (lengthOf(str)==1) str="0"+str;
return str;

Here is a macro that does this. It requires at least ImageJ 1.46e, which adds the "Label" format (draw slice labels) to the Image>Stacks>Label command.

requires("1.46e");
list = File.openAsString("");
entries = split(list, "\n");
n = entries.length;
newImage("Untitled", "8-bit Black", 512, 512, n);
for (i=1; i<=n; i++) {
setSlice(i);
items = split(entries[i-1]);
setMetadata("label", items[1]);
}
run("Label...", "format=Label x=5 y=20 font=18 use");
