Hello everyone I would like to know how to convert date time into unix timestrap? Could you show me an example please ?
Is this what you are looking for: How to convert UNIX timestamp to DateTime and vice versa?
Further urls from a google search yeild:

I have to get the max payment date on an invoice and I am having trouble with the date format. I do not need the max in this formula as I am using the format in a reporting tool that is pulling the max from what it finds for me.
Using "to_char({datefield},'mm/dd/yyyy')" works for displaying that date the way we would like BUT when you use summary function MAX it does not pull the correct date because it is looking at a string and not a date (it will think 12/3/21 is larger than 3/2/22).
Another thing I have tried is trunc - "trunc({datefield})" which gives us the correct max date but it changes the formatting. For example if the date prior to the formula being applied is "8/12/21 12:00:00:000" the trunc formula will display it as 12-08-21 which is horribly wrong.
Long story short is I need a way to change a date/time to date with the format of 'mmmm/dd/yyyy' WITHOUT converting it to a string with something like to_char. Thank you!!!!
A DATE is a binary data type consisting of 7 bytes representing: century, year-of-century, month, day, hour, minute and second. It ALWAYS has all of those components and it is NEVER stored with any (human-readable) format.
What you are seeing when a date is displayed is the client application you are using to access the database making a decision to be helpful to you, the user, and display the binary DATE provided by the database in a human-readable format.
If you want to change how the DATE is displayed then you either need to:
Change the settings on the client application that controls how it formats dates when it displays them to you; or
Change the data-type so that it is no longer a DATE (which does not have a format) to a data type where the values of the date can be formatted (such as a string). You can do this using TO_CHAR.
If you want to find the maximum then do it BEFORE applying the formatting:
SELECT TO_CHAR(MAX({datefield}),'mm/dd/yyyy')
FROM your_table;
I noticed the time format in chrome cache expiry is in format of 2021-06-19T08:38:40.980Z.
I do not recognize this time format and cant find about its conversion to UTC. So, my question is what kind of time format is this one. And how to convert it to UTC?
That is the ISO 8601 extended date time format. It also conforms to the RFC 3339 timestamp format, and the ECMAScript date time string format. Basically, that's the standard, most preferred way to represent a timestamp (as a string) on the Internet.
The date part is in yyyy-MM-dd format (year, month, day).
The T stands for "Time" and separates the date part from the time part.
The time is in HH:mm:ss.fff format (hour of 24-hour clock, minute, seconds, fractional seconds - milliseconds in this case).
The Z stands for "Zulu", another name for UTC. It indicates that the date and time before it are represented in UTC.
Thus, you do not need to convert it. The value is already in UTC.
I'm importing SQL data into Spotfire Analyst. All of the date and time fields are in the form of a Unix timestamp. What's the best way to convert this into an actual date format that I can manipulate in Spotfire?
Utilizing a calculated column you can calculate the datetime based on the UNIX epoch.
We simply add our seconds to the DateTime of the UNIX epoch (JAN 01 1970 00:00:00 UTC) to get the result. Below is an example of the UNIX time when I started writing this post.
DateAdd("second",1429733486,DateTime(1970,1,1,0,0,0,0))
The below is what should work for you:
DateAdd("second",[UNIX_TIMESTAMP_COLUMN],DateTime(1970,1,1,0,0,0,0))
Keep in mind these dates produced will be in the UTC timezone as per the JAN 1 1970 epoch. If you need them in your local time zone you may have to adjust accordingly with further DateAdd functions adding/subtracting time as per current conversions. Also, if you observe daylight savings time you may need to add some extra case logic to handle that as well.
Please let me know if you have any questions or need further clarification.
In 7.0 and later you can use
FromEpohTimeSeconds([UNIXDATE])
or
FromEpohTimeMilliseconds([UNIXDATE])
I ran an SQL Query for Oracle which consists of Invoice date and Check date. When these data are copied on to an Excel Spreadsheet as text, it's dispayed as ex: "13-10-31" (Oct 31, 2013). However, when converted to date format, it's displayed as "10/13/1931". I've tried different date types but it always recognizes as the first part of the text as the day, then month, then year. I need these values to be setup as a date format as I need to calculate Days Payable Outstanding and other related ratios.
Is there any way to convert these values so that Excel recognizes the day, month, and year correctly? Would there be a macro that could automate this process for existing data and data that will be added in the future?
Thank you in advance.
Firstly, I hope the data type of your date column is DATE.
Secondly, the date should always have year as YYYY and not just YY. The world has already learned from Y2K bug.
If above two points are met, then while displaying use to_char(date_column, 'mm/dd/yyyy'). Thus, with YYYY format, there won't be any confusion between year and other fields.
I have an online temperature logger that publishes the date and time of last measurement in a file.
I need to find the date and time stamp in the html file using VBscript, and then check if it's older then 2 hours comparing to current time.
Example date format: 12.04.2013 16:45
You could extract the timestamp with a regular expression
\d{2}\.\d{2}\.\d{4} \d{2}:\d{2}
However, due to the characteristics of HTML this is prone to error (line-wrapping, inline tags, …), so a better approach would be to extract the date from the HTML using DOM methods (e.g. getElementsByTagName().
Once you have the date string, you can use the DateDiff function to calculate the difference to the current timestamp:
DateDiff("h", datestring, Now)
