DST times not showing dm: times with 2 AM

[anmac1789]

Everything isn't viewing DST times properly. For example, in 2024, EST switches to EDT in East Coast North America at March 10, 2024 @ 2 AM (second Sunday of the month)

The results show date modified times with 1 AM when it should show times with 2 AM. How to fix this ? What is going on here ?

Also, how can I show files with date modified times of (1st sunday, 2nd sunday of x month) ?

[void]

Does Everything match the date modified timestamp from Windows Explorer?

To find date modified on the first Sunday:

WEEKDAY($dm:)+(((DAY($dm:)-1)/7)*7)==0

To find date modified on the second Sunday:

WEEKDAY($dm:)+(((DAY($dm:)-1)/7)*7)==7

How do I find any windows explorer files with date modified around 2 AM on March 10 when I use everything to find those types of files ? lol

[void]

2am-3am doesn't exist on this day.
Windows converts 2am-3am to 1am-2am


Everything converts your search dm:2024-03-10T02 to a filetime for comparison.
The date modified search starts at 2024-03-10T02 with a one-hour range.
However, due to the filetime conversion, this ends up searching for:
dm:>=2024-03-10T01 with a one-hour range



Please try the following search instead:

dm:2024-03-10 dmhour:2

This shouldn't match anything as this hour doesn't exist on this day.



-or-


Search for a larger range and sort by date modified:

dm:2024-03-10T01..2024-03-10T04

What does the

==0

and

==7

do?

[void]

== means compare

0 is the first Sunday.
7 is the second Sunday.

[anmac1789]

== means compare

0 is the first Sunday.
7 is the second Sunday.

== does this make the expression equal to 0 or 7 ? How does that function work ? whats the logic?

Also, is there an easier way to combine all these searches:

"beginning of the year until 2nd Sunday of March of any given x year" = EST (standard time) (DST off)

"From 2nd Sunday of March until 1st Sunday of November of any given x year" = EDT (daylight time) (DST on)

"1st Sunday of November until the end of any given x year" = EST (standard time) (DST off)

It's somewhat been covered already, but EBV uses filetime internally if I understand it correctly.
This is then converted to a user-friendly version or..something.
You can see this in Everything by looking at a time range of say 01-03. It may jump from 01 to 02 or 01 to 03.
It will jump back around October, I believe 27th but I cba to look it up again.
Something similar happened in my foobar2000, I think it also uses the same filetime system internally. At least Playback Statistics exports in it.

Fun? fact, it currently starts with 1337.

I'm sorry I'm a bit lost. Could you explain in easier terms for a 5 year old lol

[void]

Everything will evaluate the expression when using $dm: in your search.

When the expression evaluates as true the result is added.
When the expression evaluates as false the result is not added.

The following will evaluate as true:
1==1
7==7
( == is equal to )

The following will evaluate as false:
1==0
0==7
1==7



It might be easier to see how

WEEKDAY($dm:)+(((DAY($dm:)-1)/7)*7)==0

works by showing these values in a temporary column.

Please try including the following search:

addcolumn:a a:=WEEKDAY($dm:)

The week day as a number is shown in column A
(Everything is incorrectly using the Windows week day numbers 0=Sunday, I will switch this to Excel format 1=Sunday in the next alpha update)



To view the week, please try including the following in your search:

addcolumn:a a:=((DAY($dm:)-1)/7)

The first week will be 0, then second week 1, etc...



If you multiply the week by 7 and add the weekday you can work out the first Sunday, second Sunday etc..

addcolumn:a a:=WEEKDAY($dm:)+(((DAY($dm:)-1)/7)*7)

Thank you for clarifying. How do I combine this into a date range such as from Jan 1, 2018 to the 1st Sunday of March 2018? From 1st Sunday of March 2018 to 2nd Sunday of November 2018 ?

[void]

There's no easy way to do this in Everything.

Lookup the 1st Sunday of March 2018 and be specific with your search range in Everything:

dm:2018-01-01..2018-03-04

[anmac1789]

alright thank you, will a feature such as this come in the next release of everything ?

[void]

dm:>=2018-01-01 $dm:<DATE(2018,3,1)+(8-(WEEKDAY(DATE(2018,3,1)-840000000000)+1))*840000000000

Replace 2018,3 with your year,month.
