The second layer encodes that number as a sequence of bits or decimal digits.Īs is standard with UTC, this article labels days using the Gregorian calendar and counts times within each day in hours, minutes, and seconds. The first layer encodes a point in time as a scalar real number which represents the number of seconds that have passed since 00:00:00 UTC Thursday, 1 January 1970. Two layers of encoding make up Unix time.

It is the number of seconds that have elapsed since the Unix epoch, excluding leap seconds. Unix time (also known as Epoch time, Posix time, seconds since the Epoch, or UNIX Epoch time ) is a system for describing a point in time. It was celebrated in Copenhagen, Denmark at a party held by DKUUG (at 03:46:40 local time). The conversion formula for time to Unix time works exactly the same in Google Sheets as in Excel.Unix time passed 1 000 000 000 seconds on. To view it in date format, simply change the format of the cell to Date or your required custom format from the Number Format by accessing it through the Home TabĪfter changing the format of the numeric values of the Excel date & time, we get the following Excel date and timeĬonvert Excel Time to Unix Time in Google Sheets The resultant value, we got after the calculation, is in the serial date number format. Once we have the numeric value of the Epoch date, we’ll add these two values Now, we calculate the numeric value of the Epoch date through DATE function =DATE(1970,1,1)

Inversely, we can convert the Unix time to Excel time with the help of the following formula: =(B3/86400)+DATE(1970,1,1)įirst, the Unix timestamp is divided by the total number of seconds in a day, i.e. =1283299200 Convert Unix Time to Excel Time This is the total number of seconds, we get, between two dates

In the same way, the calculation of the numeric value of Epoch date is subtracted from the given Excel time’s numeric value =(B5-DATE(1970,1,1))Īfter that, the difference calculated from above is multiplied by 86400 to get the resultant value in seconds This can be done by using the DATE function. The first step in the conversion of Excel time to Unix time is to calculate the numeric value of the Epoch date.
