Rounding Time on quarters of an hour

Hello altogether,

is there a way in RapidMiner to round time? So that for example 00:07, 00:17, 00:31 looks like that 00:15, 00:30, 00:45 (up-rounding every time)

Thank you! :-)

Re: Rounding Time on quarters of an hour

I already used the date to numerical operator (minute relative to day), maybe from this startpoint we can find a solution?

Hi,

i think you can use Generate Attributes for this. Might be a longer equation wth quite some date_get and date_set involved..

Here's a mini example process showing a way to do this. The key is to use Unix times when calculating.

Re: Rounding Time on quarters of an hour

While this is one way to do it, another even simpler way would be to use Date to Numerical to extract the minute relative to the hour from the original date/time stamp, and then use simple modulus division (dividing by 15) inside Generate Attributes to generate an attribute housing the quarter hour value.  If desired then you could use another function to round it the way you want (e.g., round vs floor vs ceiling depending on your desired rounding behavior).
