Javascript date format like ISO but local

Question

how do I format a javascript date like ISO format, but in local time?

with myDate.toISOString() I am getting the time as: "2012-09-13T19:12:23.826Z"

but here, it is 22:13, so how do I include the timezone in above format?

I ended up doing...

pad=function(e,t,n){n=n||"0",t=t||2;while((""+e).length<t)e=n+e;return e} c = new Date() c.getFullYear()+"-"+pad(c.getMonth()+1)+"-"+pad(c.getDate()-5)+"T"+c.toLocaleTimeString().replace(/\D/g,':')+"."+pad(c.getMilliseconds(),3)

No library required! For some Date object, e.g. t = new Date()

• convert the local time zone offset from minutes to milliseconds

  z = t.getTimezoneOffset() * 60 * 1000

• subtract the offset from t

  tLocal = t-z

• create shifted Date object

  tLocal = new Date(tLocal)

• convert to ISO format string

  iso = tLocal.toISOString()

• drop the milliseconds and zone

  iso = iso.slice(0, 19)

• replace the ugly 'T' with a space

  iso = iso.replace('T', ' ')

Result is a nice ISO-ish format date-time string like "2018-08-01 22:45:50" in the local time zone.
