Tags: data · date · Excel · microsoft · time · timestamp · unix Today, I had the problem of converting a timestamp to a readable time format inside excel. Not quite as easy as I would have hoped for, but the solution is fairly painless An Excel date can be converted with the (unusual) origin of as.Date(myDate, origin=1899-12-30), which is implemented here. Microsoft Excel supports two different date systems, the 1900 date system and the 1904 date system. In the 1900 date system, the first day that is supported is January 1, 1900. A date is converted into a serial number. If you are importing data from Excel, you may have dates that are in a numeric format. We can still use as.Date to import these, we simply need to know the origin date that Excel starts counting from, and provide that to as.Date. For Excel on Windows, the origin date is December 30, 1899 for dates after 1900. (Excel's designer thought 1900 was a leap year, but it was not.) For Excel on Mac.

Only if you actually read the content of this page does it become obvious that the actual formula should be something else. To keep the time portion of the timestamp, the formula should be this.
  2. Converting dates entered as strings into numeric dates in R is relatively simple for a single string and for a vector of strings if you have consistent date information. It is far trickier if the date information is represented inconsistently. I'll discuss common pitfalls and give helpful tips to make working with dates in R less painful. Finally, I introduce some code that my colleagues and I.
  3. Working with dates and times in R can be frustrating! This isn't R's fault; dates and times are naturally complicated.

So, I can at least go from mongo::Date_t to boost::posix_time::ptime
  2. Show the differences in POSIX times between zoned and unzoned datetime values. The best practice is to specify a time zone for a datetime array before calling posixtime. Create a datetime array and specify its time zone. t1 = datetime('2016-07-29 10:05:24') + calmonths(1:3); t1.TimeZone = 'America/New_York' t1 = 1x3 datetime 29-Aug-2016 10:05:24 29-Sep-2016 10:05:24 29-Oct-2016 10:05:24.

A compound date+time observation is represented in R as an object of class POSIXct.A date observation (without time) is represented as an object of class Date. # current time now = Sys.time() class(now
  4. The date and time data types datetime, duration, and calendarDuration support efficient computations, comparisons, and formatted display of dates and times. Work with these arrays in the same way that you work with numeric arrays. You can add, subtract, sort, compare, concatenate, and plot date and time values. You also can represent dates and times as numeric arrays or as text. For more.

The Unix epoch (or Unix time or POSIX time or Unix timestamp) is the number of seconds that have elapsed since January 1, 1970 (midnight UTC/GMT), not counting leap seconds (in ISO 8601: 1970-01-01T00:00:00Z). Literally speaking the epoch is Unix time 0 (midnight 1/1/1970), but 'epoch' is often used as a synonym for 'Unix time'. Many Unix systems store epoch dates as a signed 32-bit. X = convertTo (D,dateType) converts the datetime values in D to the numeric representation specified by dateType and returns a numeric array. For example, if dateType is 'posixtime', then convertTo converts each element of D to the number of seconds that have elapsed since the epoch of January 1, 1970, 00:00:00 UTC
