call Logfile_getDateTimeStr(character(len=28)(OUT) :: dateTimeStr)
Get a string that contains the current date and time in the same format used in Logfie_stamp messages. This interface is meant for use by code outside the Logfile unit that wants to generate messages in the format of the Logfile unit but circumventing the Logfile_stamp interface.
dateTimeStr - the date and time string is returned here.
Currently, the caller could just call current_date_time directly to the same effect as calling this subroutine, with the following difference: o The string returned by this implementation is enclosed in [ square brackets ].
