<> So if Beatrice only wants to display the time of day: *********** clear* //construct your variable inp str18 mydate "30dec1899 09:30:14" end gen double newdate=clock(mydate, "DM18Yhms") format newdate %tc //only want time of day... format newdate %tcHH:MM:SS l, noo *********** As she can see here, this is just -format-ting, not changing the values. If Beatrice wanted to hold the time permanently, she can -tostring- the thing via -tostring newdate, generate(mynewdate) force format(%tcHH:MM:SS)- HTH Martin -----Original Message----- From: owner-statalist@hsphsun2.harvard.edu [mailto:owner-statalist@hsphsun2.harvard.edu] On Behalf Of Martin Weiss Sent: Samstag, 21.

If so, it is numeric, and -split- only works for strings. What you showed in your post as 30dec1899 09:30:14 is really di %20.0fc clock("30dec1899 09:30:14", "DM18Yhms") = -1,893,508,186,000 So what you really want is to extract a component, not split a string, as in -help dates_and_times, mark(extracting)-.

August 2010 17:57 To: statalist Subject: st: Remove part of a string variable Dear All, when I upload my data into Stata from my Access file (using the odbc function) the time variable that I have becomes: 30dec1899 09:30:14 And it is in a double format. I want to remove from my variable time the part 30dec1899. I tried with generate splitat and with split time, p("30dec1899") but they don't work. Could you please help me? Thank you very much.
