How to calculate elapsed time(including time and date)?

[ldragon]

Hi all,

I want to realize a function that can calculate the elapsed time which include time and date.Below is my thought:get the current time and date and store it to a .txt file then using the latest time and date subtract the time and date stored in the .txt file.how can realize it using the simplest way?I'm using LV7.1.
