This utility struct provides a namespace for a suite of functions operating on objects of type Datetime.
Declared in <bdlt_datetimeutil.h>
struct DatetimeUtil;| Name | Description |
|---|---|
convertFromTm | Load into the specified result the value of the specified timeStruct. Return 0 on success, and a non-zero value with no effect on result if timeStruct is invalid or otherwise cannot be represented as a Datetime. Values in fields tm_wday, tm_yday, and tm_isdst are ignored. The time 24:00:00 will be recognized, and leap seconds (i.e., values in tm_sec of 60 or 61) which can otherwise be represented as a Datetime will cause the conversion to succeed with the result "rolling over" into the zeroth second of next minute. Note that time zones are irrelevant for this conversion. |
convertToTm | Return or load into the specified result the value of the specified datetime expressed as a bsl::tm. Each field in the result is set to its proper value except tm_isdst, which is set to -1 to indicate that no information on daylight saving time is available. A time value of 24:00:00:00 will be converted to 0:00:00. Note that time zones are irrelevant for this conversion. |
fromYmdHms | Return an optional having a Datetime with the specified year, month, day, hour, minute, second, and the optionally specified millisecond and microsecond, if those form a valid Datetime (see Datetime::isValid); otherwise return an optional without a value. |
