Generate and return .true.
if the hour in the current or the input time zone (-720 : +840)
is Ante Meridiem (before noon).
- Parameters
-
[in] | zone | : The input scalar or array of arbitrary shape of type integer of default kind IK containing the time zone of interest in units of minutes.
(optional, default = the current local time zone.) |
[in] | julianDay | : The input scalar or array of arbitrary shape of type real of default kind RK containing the (possibly proleptic) Julian Day.
(optional, default = the current locale Julian Day.) |
- Returns
isMorning
: The output scalar or array of the same rank as input array-like arguments, of type logical
of default kind LK. It is .true.
if and only if the current time or the time corresponding to the input zone
or julianDay
or both represents represents morning.

This module contains classes and procedures for computing, manipulating, and styling dates and times.
- Warning
- The
pure
procedure(s) documented herein become impure
when the ParaMonte library is compiled with preprocessor macro CHECK_ENABLED=1
.
By default, these procedures are pure
in release
build and impure
in debug
and testing
builds. The procedures under this generic interface are always impure
when there is no input argument.
-
The conditions
-12 * 60 < zone
and zone < +14 * 60
must hold for the corresponding input arguments.
This condition is verified only if the library is built with the preprocessor macro CHECK_ENABLED=1
.
