# time older than by days

i am confused how to calculate if "OTime=2022.05.20 22:00" is older than 3 days by TimeCurrent()

i tried

`((TimeCurrent()-OTime)-(2*86400))+TimeCurrent()`

or

`(TimeCurrent()-OTime)+(TimeCurrent()-(2*86400))`

forgot about my calculations its totally fail i just want to use 'if  expression' date(OTime) is older/greater than 3  days  by TimeCurrent()

One solution:

```(TimeCurrent () - OTime) > (86400 * 3)
```

Sorry for missing the code button again. I am on mobile.

Don't hard code numbers. Write self-documenting code. You should be able to read the code out loud and have it makes sense.

`oTime < TimeCurrent() - 3 * PeriodSeconds(PERIOD_D1) // oTime is older than 3 days ago.`
The question is ambiguous. Do you mean 3 days or 3 trading days.
`iBarShift(_Symbol, PERIOD_D1, oTime) > 3 // oTime is older than 3 trading days ago.`

Hey also look at CDateTime in Include/Tools/...
There is a brilliant solution where the current Time is resolved into MqlDatetime struct, where every time unit is displayed in int numbers and you have an Increment/Detrement method for every unit(say hours/days).

But, the MqlDateTime is all public which means you can show every seconds value at every point in time.
