time normalize

[sujani]

I already posted a question,but never tried the solutions suggested
until recently.I am looking for a way to normalize the time on my
different sets of data.(The "align waveform timestamps" doesn't work
for my case.)
Each of my sets of data start and end at different times.I need a way
to normalize the start and end times(so that everything has the same
start and end times).Any suggestions?
