Timezone | Arduino library to facilitate time zone conversions

kandi X-RAY | Timezone Summary
The Timezone library is designed to work in conjunction with the Arduino Time library, which must also be installed on your system. This documentation assumes some familiarity with the Time library. The primary aim of the Timezone library is to convert Universal Coordinated Time (UTC) to the correct local time, whether it is daylight saving time (a.k.a. summer time) or standard time. The time source could be a GPS receiver, an NTP server, or a Real-Time Clock (RTC) set to UTC. But whether a hardware RTC or other time source is even present is immaterial, since the Time library can function as a software RTC without additional hardware (although its accuracy is dependent on the accuracy of the microcontroller's system clock.).

QUESTION
I have been using github actions for quite sometime but today my deployments started failing. Below is the error from github action logs
...ANSWER
Answered 2022-Mar-16 at 07:01First, this error message is indeed expected on Jan. 11th, 2022.
See "Improving Git protocol security on GitHub".
January 11, 2022 Final brownout.
This is the full brownout period where we’ll temporarily stop accepting the deprecated key and signature types, ciphers, and MACs, and the unencrypted Git protocol.
This will help clients discover any lingering use of older keys or old URLs.
Second, check your package.json
dependencies for any git://
URL, as in this example, fixed in this PR.
As noted by Jörg W Mittag:
For GitHub Actions:There was a 4-month warning.
The entire Internet has been moving away from unauthenticated, unencrypted protocols for a decade, it's not like this is a huge surprise.Personally, I consider it less an "issue" and more "detecting unmaintained dependencies".
Plus, this is still only the brownout period, so the protocol will only be disabled for a short period of time, allowing developers to discover the problem.
The permanent shutdown is not until March 15th.
As in actions/checkout issue 14, you can add as a first step:
QUESTION
I am trying to run a python async app with an asyncioscheduler scheduled job but the APScheduler fails during build because of this error:
'Only timezones from the pytz library are supported' error
I do include pytz in my app and i am passing the timezone. What is causing the error?
I am calling the asyncioscheduler in a class where i create job manager:

Answered 2021-Aug-18 at 16:21Ok so it required a dependency tzlocal==2.1 so it could get local timezone, i assume for some reason the version that the module has does not work on my system
QUESTION
Question in short
I have migrated my project from Django 2.2 to Django 3.2, and now I want to start using the possibility for asynchronous views. I have created an async view, setup asgi configuration, and run gunicorn with a Uvicorn worker. When swarming this server with 10 users concurrently, they are served synchronously. What do I need to configure in order to serve 10 concurrent users an async view?
Question in detail
This is what I did so far in my local environment:
- I am working with Django 3.2.10 and Python 3.9.
- I have installed
gunicorn
anduvicorn
through pip - I have created an
asgi.py
file with the following contents
ANSWER
Answered 2022-Feb-06 at 21:43When running the gunicorn
command, you can try to add workers
parameter with using options -w
or --workers
.
It defaults to 1
as stated in the gunicorn documentation. You may want to try to increase that value.

QUESTION
We can create Instant from Clock. Clock has a timezone.
...ANSWER
Answered 2022-Jan-24 at 21:50Instant
You said:
The output gives the same instant:
An Instant
is a moment as seen in UTC, that is, with an offset from UTC of zero hours-minutes-seconds. So your code makes no use of your specified time zones.
ZonedDateTime
Instead, try ZonedDateTime
. This class does make use of the time zone. For example, calling ZonedDateTime.now()
captures the current moment as seen in the JVM’s current default time zone. Calling ZonedDateTime.now( myClock )
captures the current moment tracked by that Clock
object as seen through that Clock
object’s assigned time zone.

QUESTION
There are many warnings out there about not using new Date(string)
(or the equivalent Date.parse(string)
in javascript because of browser inconsistencies. MDN has this to say:
It is not recommended to use Date.parse as until ES5, parsing of strings was entirely implementation dependent. There are still many differences in how different hosts parse date strings, therefore date strings should be manually parsed (a library can help if many different formats are to be accommodated).
However when you read on, most of the warnings about implementation-specific behaviour seem to be for these scenarios:
- Old browsers (like, pre-ES5 old)
- Non-ISO 8601 inputs (e.g.
"March 6th 2015"
) - Incomplete ISO 8601 inputs (e.g.
"2015-06-03"
, without the time or timezone)
What I would like to know is, given these two assumptions:
- Modern browsers (say, anything from 2020 onwards)
- Full ISO 8601 inputs (e.g.
"2021-11-26T23:04:00.778Z"
)
Can I reliably use new Date(string)
?
ANSWER
Answered 2021-Nov-27 at 00:19Yes. The format of acceptable Date strings in JavaScript is standardized:
ECMAScript defines a string interchange format for date-times based upon a simplification of the ISO 8601 calendar date extended format. The format is as follows:
QUESTION
I have a dataframe that has a timezone-aware index, and when I try to insert a new row into this dataframe, it doesn't work, instead changing the type of the index to 'object'
(ie, it can't add in the row into the current type).
MRE below:
...ANSWER
Answered 2021-Nov-26 at 14:50Timestamp
objects are certainly of type 'object'
, and it is possible you cannot escape the index to take this type if you use Timestamp
s as index.
By "timestamp configuration" I understand "timezone", and that you want to insert new times in the same timezone.
Either you know the timezone from the start and data of all rows come from a source known to be from the same timezone. In that case you can specify the same timezone when you instantiate the
Timestamp
s.Or you do not know the timezone of the data in the first place, and you have new data coming from another source, so potentially from a different timezone, that you certainly know about. Mixing timestamps from different timezones is not a problem, since timezones should be taken into account when you compare them with one another. You can still localize them all later to a timezone you prefer.
QUESTION
First, I want to state that I know the Java Calendar class is being supplanted by other libraries that are arguably better. Perhaps I've stumbled upon one of the reasons Calendar has fallen out of favor.
I ran into frustrating behavior in Calendar as it regards to the overlapping hour at the end of daylight savings time.
...ANSWER
Answered 2021-Nov-26 at 16:00As you noted, Calendar
was supplanted years ago by the java.time classes defined in JSR 310 (unanimously adopted). And as you note there are many reasons to avoid using Calendar
& Date
etc.
If you must have a Calendar
object to interoperate with old code not yet updated to java.time, convert after doing your work in java.time.
Specify your desired time zone. Note that US/Pacific
is merely an alias for the actual time zone, America/Los_Angeles
.

QUESTION
I wanted to parse string datetime & timezone with Arabic-Hindu digits, so I wrote a code like this:
...ANSWER
Answered 2021-Nov-09 at 06:15Your dateTime
string is wrong, misunderstood. It obviously tries to conform to the ISO 8601 format and fails. Because the ISO 8601 format uses US-ASCII digits.
The classes of java.time (Instant
, OffsetDateTime
and ZonedDateTime
) would parse your string without any formatter if only the digits were correct for ISO 8601. In the vast majority of cases I would take your avenue: try to parse the string as it is. Not in this case. To me it makes more sense to correct the string before parsing.
