Differnce in time while writing and reading time to a .txt file

[vindsan]

Hi,

I have done a code to store date in a .txt file and then read from that txt file and output that date into a time stamp indicator. But the problem the input time and output time are not same. I dont know why. I have uploaded the code. Thanking You in advance.

Your problem is that you use "%T" in your format string.  %T is absolute time which actually has the time first and then the date.  

You need to change that to use the correct time format that matches the way you save time.  I got your VI working when I replaced "%T" with "%<%m/%d/%y %I:%M:%S %p>T".  Look up the format codes for time format string for more details on what each part means.

The Format Date/Time String defaults to "%c".  Therefore the Scan From String should have the format of "%<%c>T" to match.

However, %c uses the system format.  This is generally a bad idea.  If I tried to read the same string on my machine, it would fail.  So the format should be explicit on the Format Date/Time String and the Scan From String to make it consistant on all systems.

Thank You very much. I got it. I got it using %<%c>T. So when u said the format should be explicit on the Format Date/Time String and the Scan From String to make it consistant on all systems, I didnt understand. What does it mean.Which format should I use. Thanking You.

What he's referring is that when your formats should be explicit in both the write and read steps.  Look at the image for an example on a consistent/explicit %c format.
