Public Static Functions

static _ASYNCRTIMP datetime __cdecl utc_now ()

Returns the current UTC time.

static inline interval_type utc_timestamp()

Returns seconds since Unix/POSIX time epoch at 01-01-1970 00:00:00. If time is before epoch, utc_timestamp_invalid is returned.

static _ASYNCRTIMP datetime __cdecl from_string (const utility::string_t &timestring, date_format format=RFC_1123)

Creates datetime from a string representing time in UTC in RFC 1123 or ISO 8601 format.

Returns

Returns a datetime of zero if not successful.

static _ASYNCRTIMP datetime __cdecl from_string_maximum_error (const utility::string_t &timestring, date_format format=RFC_1123)

Creates datetime from a string representing time in UTC in RFC 1123 or ISO 8601 format.

Returns

Returns datetime::maximum() if not successful.
