add_days(Timestamp::datetime() | timestamp(), D::integer()) -> datetime()
Add some days to the supplied datetime().
add_months(Timestamp::datetime() | timestamp(), M::integer()) -> datetime()
Add some months to the supplied datetime().
add_time(Timestamp::calendar:datetime(), H::integer(), M::integer(), S::integer()) -> calendar:datetime()
Add some time to the supplied calendar:datetime().
add_years(Timestamp::datetime() | timestamp(), Y::integer()) -> datetime()
Add some years to the supplied datetime().
apply_duration(Datetime::datetime(), Duration::string()) -> datetime()
Return new datetime after apply duration.
format(Timestamp::datetime() | timestamp()) -> binary()
Convert a util:timestamp() or a calendar-style {date(), time()}
tuple to an ISO 8601 formatted string. Note that this function always
returns a string with no offset (i.e., ending in "Z").
parse(Bin::iodata()) -> calendar:datetime()

parse_duration(Bin::string()) -> datetime_plist()
Convert an ISO 8601 Durations string to a
parse_exact(Bin::iodata()) -> calendar:datetime()
Convert an ISO 8601 formatted string to a {date(), time()}
tuple with seconds precision to 3 decimal places
subtract_time(Datetime::calendar:datetime(), H::integer(), M::integer(), S::integer()) -> calendar:datetime()
Subtract some time from the supplied calendar:datetime().
