Unix date conversion excel formula code#
+14400 to simulate the time it would've been saved into the table during DST (effectively becomes same as GMT -4)Īny help on getting the code added for cutoff in Mar and Nov would be greatly appreciate. use the PARSEDATE and PARSEDATETIME functions to convert text into Date and Date & Time fields. SELECT = + taken a break for the time being from trying to figure out the DST cutoff with starting at 2am 2nd Sun in Mar and ending at 2am 1st Sun in Nov, but above function will correctly convert to/from DST even if current date is DST and the date to convert is nonDST: This function only supports compatibility mode dates.
IF DATEPART(m,GETDATE()) BETWEEN 4 AND 10 SET = DateDiff(ss, GetUTCDate(), GetDate())
here's snippet I've been working with to test conversion: "18000" will eventually need replaced with a var storing GMT offset*/Īnd March and 2nd Sunday or later, assumes SELECT returns 7 for Sunday (default)Īnd Nov and not yet 1st Sunday, assumes SELECT returns 7 for Sunday (default) *18000 accounts for gmt offset of -5 - 18000 being 5 hrs shown in secondsĭoesn't account for daylight savings time, but could with more effort (a case statement of some sort) This is what I've come up with so far, but need some help accommodating for specific time change (2am is cutoff for DST): Has anyone else had to deal with this before? like this: ( ( (b1 60) 60) 24) date (1970,1,1) type this formula into a cell and press enter key, and then drag the autofill handle from cell c1 to c5. *erm cough, I mean daylight savings time. To convert a unix time stamp to an excel date string in excel, you can use a formula based on the date function. Sorry for the necropost, but this is the closest topic to an issue I'm having that I could works to convert a Unix date to a Julian date, however, doesn't accommodate Daylight Savings Time so for all days that fall between 2nd Sunday in Mar and 1st Sunday in Nov, the time returned is off by an hour due to daylight wasting time.
