date , timestamp , and you can interval undertake an elective accuracy worthy of p hence specifies the quantity of fractional digits employed regarding the seconds community. Automatically, there isn’t any direct bound for the accuracy. The latest greeting directory of p is off 0 to help you six.
New period style of provides an additional solution, which is to maximum new gang of stored areas by the creating one of them sentences:
Seasons Few days Day Hours Minute Next Season So you're able to Month Big date To help you Hours Time To Second Time To Second Hr To Second Hours In order to 2nd Time In order to 2nd
