remember that Appian datestamps are inherently stored in GMT, regardless of what you do, the only difference is what you see displayed. My rule above has 2 different styles of output (depending on the GMT parameter) which was intended to accept stamps that need to be converted from GMT prior to output (since sometimes the text values we get are really a local timestamp and Appian will interpret them as a literal GMT value then convert too far).

Try this-

input - "03-04-2022 09:14:36" - Text

output - 4/3/2022 9:14 AM - DateTime

a!localVariables(
local!date: split(ri!date," "),
local!time: split(ri!date," "),
local!concat: concat(todate(local!date[1])," ",totime(local!time[2])),
split(todatetime(local!concat)," G")[1]

)

Hi Mike, Thanks for your response.

It gives the expected output, but is it is possible to save/fetch the date and time without time zone?

Input String : "2024-01-31 09:14:36"

Current output from your code : 1/31/2024 9:14 AM GMT-05:00

Expected output : 1/31/2024 9:14 AM

this isn't "parseDateTime()" which you quoted above - the function "todatetime()" (referenced in your link here) does not convert ISO-8601 date/time strings (i.e. "yyyy-mm-dd" etc), only "mm/dd/yy" style strings.

I've written it from scratch in the past, if you want (note it requires Regex Functions plug-in)

Parsing ISO-8601 date/time

RULE_Utility_parseIsoDateTime()

if(
  or(
    isnull(ri!dateTimeString),
    not(regexmatch(
      pattern: "[12]\d\d\d-[01]{0,1}\d-[0123]{0,1}\d [012]\d:[012345]\d:[012345]\d",
      searchString: ri!dateTimeString,
      regexFlags: "s"
    )) 
  ),
  null(),
  
  a!localVariables(
    local!parts: split(ri!dateTimeString, " "),
    local!dateParts: split(local!parts[1], "-"),
    local!timeParts: split(local!parts[2], ":"),
    local!gmtTime: datetime(
      local!dateParts[1],
      local!dateParts[2],
      local!dateParts[3],
      local!timeParts[1],
      local!timeParts[2],
      local!timeParts[3]
    ),
    
    if(
      ri!fromGmt,
      local!gmtTime,
      gmt(local!gmtTime)
    )
  )
)

I tried this - value(local!convertedDateTime, "MM/dd/yyyy hh:mm a") but It gives me the output as 1/30/2024 11:14 PM GMT-05:00 for this input "2024-01-31 09:14:36".

Code:

a!localVariables(
local!dateAndTime: split("2024-01-31 09:14:36", " "),
local!date: split(local!dateAndTime[1], "-"),
local!time: split(local!dateAndTime[2], ":"),
local!convertedDateTime:datetime(
local!date[1],
local!date[2],
local!date[3],
tointeger(local!time[1]),
tointeger(local!time[2]),
tointeger(local!time[3]),
),
value(local!convertedDateTime, "MM/dd/yyyy hh:mm a")
)

But my expected output is 1/31/2024 09:14 AM.

Sorry,we dont have parseDateTime function.

/* Example conversion assuming 'excelDateTimeText' is the Text variable with your date-time string */

/* First, replace the '-' with '/' to match Appian's date format */
!dateString = replace(excelDateTimeText, "-", "/");

/* Then, use the toDatetime() function to convert the string to DateTime data type */
!dateTime = toDatetime(!dateString, "MM/dd/yyyy HH:mm:ss");

/* Now, '!dateTime' is an Appian DateTime data type */

Instead of format, use value with a format string:
value(local!convertedDateTime, "MM/dd/yyyy hh:mm a")

Hi, thanks for your response. I want the output in Date time format, not as a text.

Hi, thanks for your response. It shows me like format function is not available.

Example for converting "2024-01-31 09:14:36" to "1/31/2024 9:14 AM" *

Step 1: Parse the DateTime text
!dateTime = parseDateTime("2024-01-31 09:14:36", "yyyy-MM-dd HH:mm:ss");

Step 2: Format the DateTime to desired format
!formattedDateTime = toFormattedString(!dateTime, "M/d/yyyy h:mm a");

Output the formatted DateTime
!formattedDateTime

Note:Apply this logic for each dateTime string you extract from your Excel sheet. Remember, before writing to the database, ensure that your CDT/columns designed to hold DateTime values are indeed set to accept DateTime data types.

RE: How to convert a text to dateTime

Shubham Aware — Tue, 02 Apr 2024 17:33:58 GMT

Create a dateTime local variable.
Use todatetime(text!excelDateTimeColumn) to convert text to dateTime.
Use format(local!convertedDateTime, "MM/dd/yyyy hh:mm a") to format the date.
Write the text!desiredOutput variable to the database (formatted date).
