R: lubridate::fast_strptime returns different value from base::strptime

Asked 2020-Jul-11 at 09:08

I was trying to convert a date-time characters column in a huge dataframe to POSIXct for further processing. An example of the date-time column is: "Wed Jul 01 00:10:32 UTC 2020".

Due to the large amount of rows (>5 million rows), I was trying the fastPOSIXct function in the fasttime package to speed it up. My plan was to convert the date-time character to a POSIXlt format and then use the fastPOSIXct function to process.

In the process, I found that the base::strptime and lubridate::fast_strptime returned different outcomes:

It is because fast_strptime function does not accept "a" as appliable format. If you remove the weekday name argument, it will return the same results.

It seems that when you are calling fun.max in stat_summary function it extends the plot to this particular y value.

Instead of using stat_summary, you can use geom_text and calculate the length of each group (and set their x, y positions) on the fly by using dplyr package such as:

It looks like you've lost some precision when serializing-deserializing the date over the REST interface.

A: 1534733516393
B: 1534733516000

One way to compensate for that is to discard the milliseconds:

sprintDetailDTO.startDategetTime()/1000 == startDate.getTime()/1000

When the documentation is lacking with open source projects one needs to visit the actual source code itself to see the true answer. So in regards to the various time-based data types is best to read a representative example in the source code. This particular class illustrates the usage quite well.

QUESTION

avr timer1 16bit fast PWM

Asked 2017-Aug-30 at 19:25

I am using an Atmega328p-pu. I am trying to use the timer 1 for both a 16 bit PWM as well as using the overflow inturrupt to increment a timer. My code is below, I also set the F_CPU to 8000000UL in the make file.

I would like the to have a variable that counts up for a defined amount of time and then resets and continues. so far I would expect it to count up for 7.5 seconds. I believe I should have a clock frequency of 8 MHz, then with fast PWM with a 1 prescaler and ICR1 at 5000 I would expect the inturrupt to happen at 1600 Hz. Then I let it count up for 12000 counts. I would expect this to take 7.5 seconds. but I've measured it at around 57 seconds. I'm not sure what I'm missing, maybe something in the setting of the registers, but I'm not sure where. thanks for your help,

here is what I think is most important,

Answered 2017-Aug-30 at 19:25

Whenever I'm using the internal oscillator and things are running either way (8x) faster, or way (8x) slower, I check the CKDIV8 bit setting. Almost always that's the culprit.

If using an external oscillator or clock, weird timings are often from not switching the the external clock in the fuse settings, or from having F_CPU set differently from actual frequency.

Also, off-topic a bit, but code such as this is redundant:
