Hi!
I am trying to do the following:
import tables, times
type
Person* = object
name*: string
birth_date_time*: DateTime
proc newPerson(name: string,
birth_date_time: DateTime): Person =
return Person(name: name,
birth_date_time: birth_date_time)
var family = initTable[string, Person]()
let papa = newPerson(name = "Udo",
birth_date_time = initDateTime(1, mJan, 1980, 12, 0, 0,
0, utc()))
family["Udo"] = papa
let mama = newPerson(name = "Ida",
birth_date_time = initDateTime(15, mApr, 1981, 12, 0,
0, 0, utc()))
family["Ida"] = mama
echo "Papa: " & family["Udo"].name & " - born: " &
$family["Udo"].birth_date_time
echo "Mama: " & family["Ida"].name & " - born: " &
$family["Ida"].birth_date_time
Run
It works but y get

This warning seems to be linked to the usage of DateTime as part of the object
properties (It does not show up if e.g. using a string to represent the
birth_date_time).
Should I just ignore the warning, or better try a workaround?
Background: I am building a solution that controls timing of data provision and
time series type changes. Thus, a lot of DateTime type information flying
around. Would rather prefer not messing around with strings all the time.
