Brother even blockchain training take you to the actual go case ($) Go time

The go language is the second open source programming language released by Google 2009.

The go language is optimized for programming multi-processor system applications, with go-compiled programs that are comparable to C or C + + code, and are more secure and support parallel processes. Not only can develop the web, can develop the bottom, now know is to use Golang development. The preferred language for blockchain is go, to-Tai Fang, the Super Ledger is based on the go language, and the go language version of the BTCD.

Brother even go full stack and Blockchain training courses Total 22 weeks study duration, divided into 9 learning stages, that is, the main blockchain language-go language development practice, Blockchain backend technology system-go Language high concurrency and server development, go development Zone block chain public chain (blockchain cryptography, distributed programming, Consensus algorithms, basic concepts, Golan Development), Tai Fong and smart contracts and Dapp development, blockchain distributed application development, blockchain system framework development-Super ledger and Blockchain 3.0EOS, go and blockchain interview hardening and advanced enterprise-level project combat.

Go time

Go provides support for time and time. Here are some examples.

Packagemain

Import "FMT"

Import "Time"

Funcmain () {

P:=fmt. Println

Start from getting the current time

Now:=time. Now ()

P (now)

You can provide years, months, days, etc. to create a time. Of course time

Will always be associated with the region, which is the time zone

Then:=time. Date (2009,11,17,20,34,58,651387237,time. UTC)

P (then)

You can get the various components of time

P (then. Year ())

P (then. Month ())

P (then. Day ())

P (then. Hour ())

P (then. Minute ())

P (then. Second ())

P (then. Nanosecond ())

P (then. Location ())

The output day is a few weeks, one of the Monday-sunday

P (then. Weekday ())

The following several methods determine the order of two time, accurate to the second

P (then. Before (now))

P (then. After (now))

P (then. Equal (now))

The Sub method returns two time intervals (Duration)

Diff:=now. Sub (then)

P (diff)

The size of the interval can be calculated in different units

P (diff. Hours ())

P (diff. Minutes ())

P (diff. Seconds ())

P (diff. Nanoseconds ())

You can use the Add method to add an interval to the time

Use a minus sign to indicate that time goes forward a time interval

P (then. Add (diff))

P (then. ADD (-diff))

}
