comment Why is FileNameJoin not working?
@Nasser the small space is the key. between "," and "input". (,"input") will be wrong, (, "input") will be right

WOW! That is the point! I just noticed the important small space before I came back and look at your answer. This is absolutely a "bug" I think

@Nasser That is strange! It's not only happened in my local mathematica, it also happens why I use mathematica on HPC, sometimes it did't create a file, sometimes it creates a file named "FileNameJoin[.....]"? That makes crazy

@Nasser and it shouldn't be a matter if there is already a file with the name "input" exit? Put always write, I think

@Nasser I've edited my question. aaa can be anything just for convenience. If I didn't define aaa, the aaa>>file will put 3 "a" characters into file .

@Artes Great! But it seems that ` Times[a_, Power[E, Times[Complex[0, b_], x]]] :> a z^b ` is rebundant, right?

@Mr.Wizard Yeah, it can be AbsoluteTime, and I can use`DateListPlot`. I reprocess my data, and now with date information. Herehttp://en.textsave.org/VdL

comment How to partition a list into sublists in a similar way to Histogram
@Mr.Wizard The partition is good. I need to preserve the pairs. But I am afraid I need the empty bin to plot the 5 minutes average curve like TemporalData gives. Then how to get the empty bin? The method I can think of is to artificially insert zero data to those no data time region.

@Mr.Wizard Thank you, Mr.Wizard! Your method using Binlists is quite general, I like it! It is hard to determine which answer should be accepted as the best answer. ubpdqn's answer using TemporalData is really suitable for this particular problem involving date.

@ubpdqn Thank you, ubpdqn! Your method using "TemporalData" is perfect in this problem. I made a mistake in my last reply. The second in DataList can be fractional number. So I can always add small varying quantity to the seconds to differentiate different data even in the same second.
