+FUNCTION
+<<gmtime>>---convert time to UTC traditional form
+
+INDEX
+	gmtime
+
+ANSI_SYNOPSIS
+	#include <time.h>
+	struct tm *gmtime(const time_t *<[clock]>);
+	struct tm *gmtime_r(const time_t *<[clock]>, struct tm *<[res]>);
+
+TRAD_SYNOPSIS
+	#include <time.h>
+	struct tm *gmtime(<[clock]>)
+	const time_t *<[clock]>;
+	struct tm *gmtime_r(<[clock]>, <[res]>)
+	const time_t *<[clock]>;
+	struct tm *<[res]>;
+
+DESCRIPTION
+<<gmtime>> assumes the time at <[clock]> represents a local time.
+<<gmtime>> converts it to UTC (Universal Coordinated Time, also known in some
+countries as GMT, Greenwich Mean time), then converts the
+representation from the arithmetic representation to
+the traditional representation defined by <<struct tm>>.
+
+<<gmtime>> constructs the traditional time representation in static
+storage; each call to <<gmtime>> or <<localtime>> will overwrite the
+information generated by previous calls to either function.
+
+RETURNS
+A pointer to the traditional time representation (<<struct tm>>).
+
+PORTABILITY
+ANSI C requires <<gmtime>>.
+
+<<gmtime>> requires no supporting OS subroutines.
