Functions
int	stir::time_zone_offset_in_secs ()
	returns the current time_zone in seconds (without DST)The result is independent of DST.
int	stir::current_time_zone_and_DST_offset_in_secs ()
	returns the current time_zone in seconds (taking DST into account) More...
std::string	stir::DICOM_date_time_to_DT (const std::string &date, const std::string &time, const std::string &TZ="")
	concatenate date, time and optional time_zone info.Minimal checks on format are performed, calling error() if input is incorrect.
double	stir::DICOM_datetime_to_secs_since_Unix_epoch (const std::string &str, bool silent=false)
	convert DICOM DT string to seconds since the Unix epoch (i.e. 1 Jan 1970 00:00:00 UTC) More...
std::string	stir::secs_since_Unix_epoch_to_DICOM_datetime (double secs, int time_zone_offset_in_secs=current_time_zone_and_DST_offset_in_secs())
	convert epoch to DICOM DT string in specified time zone (+3600 is CET)
DateTimeStrings	stir::DICOM_datetime_to_Interfile (const std::string &str)
	Convert from DICOM DT to Interfile.
std::string	stir::Interfile_datetime_to_DICOM (const DateTimeStrings &)
	Convert from Interfile to DICOM DT.
double	stir::Interfile_datetime_to_secs_since_Unix_epoch (const DateTimeStrings &, bool silent=false)
	convert Interfile DateTime strings to seconds since the Unix epoch (i.e. 1 Jan 1970 00:00:00 UTC)Interfile uses a format year 1900:01:01, time 02:01:00.00. More...
DateTimeStrings	stir::secs_since_Unix_epoch_to_Interfile_datetime (double secs, int time_zone_offset_in_secs=current_time_zone_and_DST_offset_in_secs())
	convert epoch to Interfile date-times string in specified time zone (+3600 is CET)
