Create date object from vectors of year, month and day values.
dtt_date_time_from_ints(
year = 1972L,
month = 1L,
day = 1L,
hour = 0L,
minute = 0L,
second = 0L,
tz = dtt_default_tz()
)An integer of the year. The default value is 1972.
An integer of the month between 1 and 12. The default value is the 1st month.
An integer of the day between 1 and 31. The default value is the 1st day.
An integer of the hour between 0 and 23.The default value is hour zero.
An integer of the minute between 0 to 59. The default value is minute zero.
An integer of the second between 0 to 59. The default value is second zero.
A string of the time zone.
A POSIXct vector
This can be very helpful when needing to create a date time column in a data frame from year, month, day, hour, minute, and second columns. Vectors must all be the same length or be of length one.
