I have separate date and time fields for an event and the data entry of that event. How do I determine the hours between the event and the data entry?
The time field is a string in standard time which I converted to a military time time field using a formula.
date is written in mm/dd/yyyy format and time is in standard time hh:mm am/pm which I've converted to HH:MM military time.
If an event happened at 12:10 pm on 12/3/2016 but it was entered at 1:25 pm on 12/5/2016, I want to see 49 Hours and 15 Minutes in my final field
DateDiff is just what you need. Something like:
DateDiff("h", DateTime({StartDate},{StartTime}), DateTime({EndDate},{EndTime}))
& " Hours and " &
DateDiff("n", DateTime({StartDate},{StartTime}), DateTime({EndDate},{EndTime})) Mod 60
& " Minutes"
This will retrieve the difference between your two dateTimes twice - Once in hours, once in minutes. Perform Mod 60 on the minutes section to get only the remainder minutes after subtracting 60 minutes for each hour.

I need to calculate the difference between 2 dates i.e creation date till todays date in hours in teradata.
((Creation_date - Current_Date) HOUR) As Open_Hour
If you just want hours:
select current_timestamp - <your timestamp> hour
If you want to get more granular, you can use hour to minute or hour to second.
I have two inputs first input is for getting the date and the second input is for getting the time of the day.
For example,
User selects date: 20 January 2019 and time: 12:30 pm.
When I convert the date input to Unix timestamp I get the timestamp for 00:00 hours on 20 January 2019.
startingDate = moment(date.startsOn).unix();
So I want to add hours that I'm getting from the user into the date timestamp.
When I try to convert hours into Unix timestamp I get a timestamp for the present day along with the hours entered by the user i.e. I get timestamp for 12:00 pm on 11 January 2019.
startingTime = moment(date.startingTime).unix();
Any suggestion how I can achieve this?
I managed to do this in this way:
As I had my starting date and time in unix format
startingDate = moment(date.startsOn).unix();
startingTime = moment(date.startingTime).unix();
I had to convert them into moment format
const date = moment.unix(this.startingDate).format('YYYY-MM-DD h:mm a');
const hours = moment.unix(this.startingTime).format('HH');
Then I added hours to my date constant
var finalTime = date.add(hours, 'hours');
Then I posted this finalTime to my API.
We require to search by day of week and time of day using SOLR.
That`s why we first convert date to UTC and then create two index fields: UTC second of day and UTC day of week.
We know what timezone user requests, so we are able to shift this required values and create query:
Monday from 4:00 to 6:00 AM in +5 timezone
is converted to search values for UTC:
(Sunday from 23:00 to 24:00) OR Monday (0:00 to 1:00)
Unfortunatelly this query will fail in timezones with daylight saving time, when timezone is shifted +5 is +6.
Is there a way how to query by correct time of day?
Only solution we could think of is add to query also date ranges, which were in summer/winter time:
((Sunday from 23:00 to 24:00) OR Monday (0:00 to 1:00)) AND (30.10.2015 TO 27.3.2016) OR Monday (0:00 to 2:00)) AND (27.3.2015 TO 30.10.2015 ) OR ... OR ... ,
where these ... represents date, when was switched from summer to winter time.
Data may be recorded in any timezone and viewed in any timezone as well
I need to prepare a yearly management report to show the total overtime (OT) work hours and minutes of all staff within time range and month.
The time format in ms sql 2000 database is as follows:
Each record will contains the FROM date & time and TO date & time
The report layout is as follows:
I had no idea how to divide and calculate the total hours & minutes within the time range as each OT records will overlap several time range and date.
Please help. Thanks.

The SQL DateDiff function can be used to compute the number of minutes, i.e.
declare #fromDT datetime
declare #toDT datetime
set #fromDT = '10/22/2011 18:30'
set #toDT = '10/22/2011 22:45'
select #fromDT,#toDT,DATEDIFF(mi,#fromDt,#toDt),
ltrim(str(DATEDIFF(mi,#fromDt,#toDt)/60))+':'+
ltrim(str(DATEDIFF(mi,#fromDt,#toDt)%60)) as HoursMin
Returns
StartTime End Time Mins HoursMin
2011-10-22 18:30:00.000 2011-10-22 22:45:00.000 255 4:15
Wikipedia gives an example of an ISO 8601 example of a repeating interval:
R5/2008-03-01T13:00:00Z/P1Y2M10DT2H30M
This is what this means:
R5 means that the interval after the slash is repeated 5 times.
2008-03-01T13:00:00Z means that the interval begins at this given datetime.
P1Y2M10DT2H30M means that the interval lasts for
1 year
2 months
10 days
2 hours
30 minutes
My problem is that I do not know exactly what is being repeated here. Does the repetition
occur immediately after the interval ends? Can I specify that every Monday something happens from 13:00 to 14:00?
The standard itself doesn't clarify, but the only obvious interpretation here is that the interval repeats back-to-back. So this recurring interval:
R2/2008-03-01T13:00:00Z/P1Y2M10DT2H30M
Will be equivalent to these non-recurring intervals:
2008-03-01T13:00:00Z/P1Y2M10DT2H30M
2009-05-01T15:30:00Z/P1Y2M10DT2H30M
(Note: my reading is that the number of repetitions does include the first occurrence)
There is no way to represent "every Monday from 13:00 to 14:00" inside of ISO 8601, but it's natural to do for a VEVENT in the iCalendar format. (If you could do that entirely within ISO 8601, then that would give rise to a slew of further feature requests)
Yes, ISO8601 does define a regular repeating interval (or as regular as a "month" can be as one of the units).
R5/2008-03-01T13:00:00Z/P1Y2M10DT2H30M
Should generate these times:
2009-05-11T15:30:00Z
2010-07-21T18:00:00Z
2011-10-01T20:30:00Z
2012-12-11T23:00:00Z
2014-02-22T00:30:00Z
It doesn't define a "start time" and "end time" like RFC5545 (iCalendar) does, or even irregular repetition like RRULE or crontab can.
You should be able to specify a weekly repetition using the ISO Week Date as a starting point, but you'll need separate repetitions for "start" and "end" times:
R/2021-W01-1T13:00:00Z/P1W
R/2021-W01-1T14:00:00Z/P1W
The first interval is for the start times: Mondays at 13:00 (starting in 2021), and the second is for the end times: Mondays at 14:00 (starting in 2021).
I'm probably being an idiot (Long Covid Brain) but isn't the obvious extension to ISO-8601 a second duration part? In the absence of the second duration, the repeats are back to back, in its presence what is actually repeating is a smaller duration event at the start of each period. e.g.
R/2021-W01-1T13:00:00Z/P1W/P1H
indefinite weekly repeat of hour long slots every Monday 1pm starting week 1 2021.
EDIT: Maybe you could even nest them ...
R/2021-W01-1T09:00:00Z/P1W/R5/P1D/P8H
Mon to Fri, 9am to 5pm, every week? Ok I'll get my coat
