Golang- time and date related functions

Golang- time and date related functions

　　Basic introduction

　　　　Description: In programming, the programmer will often use the date-related functions, such as: statistical piece of code execution time spent, and so on.
　　　　1) the time and date related functions, packets need to import time

　　　　　　

 

 

 　　　　2) time.Time type, for indicating time

　　　　　　 

 

 

 　　　　3) how to get to the other date information

　　　　　　　　

　　　　4) the date and time format
　　　　　　mode 1: Printf is used or SPrintf

　　　　　　　　

 

 

 　　　　　　Second way: using time.Format () method completes:

　　　　　　　　　　　　

　　　　　　　　The above description of the code:
　　　　　　　　"2006/01/02 15:04:05" is the respective number string is fixed, must be written.
　　　　　　　　"2006/01/02 15:04:05" This combination of each string numbers are free, so you can program according to the needs of the time and date to return

 　　　　

　　　　Constant 5) Time

const ( 
　　　　　　Nanosecond the Duration =. 1 // ns 
　　　　　　Microsecond = 1000 * Nanosecond // sec 
　　　　　　Millisecond = 1000 * Microsecond // ms Second = 1000 * Millisecond // sec 
　　　　　　Minute = 60 * Second // min 
　　　　　　Hour = 60 * Minute // hours 
　　　　)

　　　　　　The effects of constants: the program can be used to obtain a given time period of time such as 100 milliseconds want Millisecond Time * 100.
　　　　. 6) used in combination at Sleep time constant

　　　　　　

 

 　　　　7) time Unix and methods UnixNano

　　　　　　

　　　　　　 

 

 　　　　　　The results obtained:
