Explanation:

Var datelocalnow = new Date (); create a time class

Var datelocalyear = datelocalnow. getFullYear (); get the year

Var datelocalmonth = (datelocalmonth = "0" + (datelocalnow. getMonth () + 1). substr (datelocalmonth. length-2, 2); get month

Var datelocalday = (datelocalday = "0" + datelocalnow. getDate (). substr (datelocalday. length-2, 2); get date

Var datelocalweekday = datelocalweek [datelocalnow. getDay ()]; get week

Datelocalnow. getHours () Get hour

Datelocalnow. getMinutes () minutes

Datelocalnow. getSeconds () get seconds
