addMonths fns is not returning correct UTC time

ANSWER

Answered 2022-Mar-05 at 14:02

The difference between CEST and UTC is simply one hour.

The difference is two hours: Central European Summer Time (CEST, UTC+02:00).

You went from CET time (one hour ahead) on Mar 05 2022 to CEST summer time (two hours ahead) on 2022-04-05.

Central European Time (CET) is a standard time which is 1 hour ahead of Coordinated Universal Time (UTC).

As of 2011, all member states of the European Union observe summer time (daylight saving time), from the last Sunday in March to the last Sunday in October. States within the CET area switch to Central European Summer Time (CEST, UTC+02:00) for the summer.

C++ vs. python: daylight saving time not recognized when extracting Unix time?

I'm attempting to calculate the Unix time of a given date and time represented by two integers, e.g.

testdate1 = 20060711 (July 11th, 2006)

testdate2 = 4 (00:00:04, 4 seconds after midnight)

localtime sets timeinfo->tm_isdst to that of the current time - not of the date you parse.

Don't call localtime. Set timeinfo->tm_isdst to -1:

The value specified in the tm_isdst field informs mktime() whether or not daylight saving time (DST) is in effect for the time supplied in the tm structure: a positive value means DST is in effect; zero means that DST is not in effect; and a negative value means that mktime() should (use timezone information and system databases to) attempt to determine whether DST is in effect at the specified time.

See the code example in https://en.cppreference.com/w/cpp/chrono/c/mktime

ANSWER

If you look at values.yaml file for MariaDB helm chart, you can see 3 types of ConfigMap:

initdbScriptsConfigMap - to supply Init scripts to be run at first boot of DB instance
primary.existingConfigmap - to control MariaDB Primary instance configuration
secondary.existingConfigmap - to control MariaDB Secondary instance configuration

Thus, each of them is intended for the specific purpose and it is not a good idea to mix these settings in one ConfigMap.

I recommend you to create new ConfigMap eramba2 for custom my.cnf with all necessary values (not only new) as below.

Python datetime utcnow vs Luxon Datetime.fromMillis?

Asked 2021-Dec-11 at 09:00

I'm trying to wrap my head in understanding the implication of using .utcnow vs. .now on Python's DateTime.

Here's the reason for my confusion: I live in France. Right now, we have a +1 hour on the UTC timezone (CET timezone in winter (now) / CEST (+2) timezone in summer).

If I take the following value :

No, epochconverter.com isn't doing anything. The value 1639063064 really does represent 2021-12-09T15:17:44Z. That's not the value you want.

I'm no Python expert, but I believe the problem is the combination of this utcnow() behavior (emphasis mine):

Return the current UTC date and time, with tzinfo None.

This is like now(), but returns the current UTC date and time, as a naive datetime object.

And this timestamp() behavior:

Naive datetime instances are assumed to represent local time and this method relies on the platform C mktime() function to perform the conversion.

It sounds like you want to follow this advice:

An aware current UTC datetime can be obtained by calling datetime.now(timezone.utc).

So just change your first line to:

validated_data is returning empty OrderedDict for nested fields with Django Rest Framework

Asked 2021-Nov-09 at 14:22

Can someone help me figure out why some fields are not parsed correctly using nested serializers with Django and Django-rest-framework?

I've researched the issue on SO, and the only cause for this happening I've found is that the request is sent as Form-data and not Json, but I've checked that response.content_type equals application/json - so this shouldn't be the issue here.

This is what my validated_data looks like (note that 3 of the fields only contain an empty OrderedDict):

Converting UTC timestamps to the users time zone in ELM

I am working on a calendar written im ELM, that needs to show entries it gets from a backend over a REST interface. All times I get from the backend are in UTC, and I need to show them to the user in the user's time zone.

I implemented this by getting the timezone off the user once at the beginning with the following task:

Rather than using the fixed offset that Time.here provides, an alternative is to pass in the result of Intl.DateTimeFormat().resolvedOptions().timeZone (MDN) through the flags at startup.

Using justinmimbs/timezone-data, parsing it on the Elm side may look something like:
