Hi all
I want to do a simple substitution in awk but I am getting unexpected output. My function accepts a time and then prints out a validation message if the time is valid. However some times may include a : and i want to strip this out if it exists before i get to the validation. I have shown a small sample of my function below which is giving the unexpected output. When this function is called with 23:01 the first print time gives 23:01 but the second gives a 1. What i want is simply 2301.
Can anyone let me know what im doing wrong.
Thanks

zdump
ZDUMP(8) BSD System Manager's Manual ZDUMP(8)NAME
zdump -- time zone dumper
SYNOPSIS
zdump [--version] [-v] [-c [loyear,]highyear] [zonename ...]
DESCRIPTION
zdump prints the current time in each zonename named on the command line.
These options are available:
--version Output version information and exit.
-v For each zonename on the command line, print the time at the lowest possible time value, the time one day after the lowest possi-
ble time value, the times both one second before and exactly at each detected time discontinuity, the time at one day less than
the highest possible time value, and the time at the highest possible time value, Each line ends with
isdst=1
if the given time is Daylight Saving Time or
isdst=0
otherwise.
-c [loyear,]highyear
Cut off the verbose output near the start of the given year(s). By default, the program cuts off verbose output near the starts
of the years -500 and 2500.
LIMITATIONS
The -v option may not be used on systems with floating-point time_t values that are neither float nor double.
Time discontinuities are found by sampling the results returned by localtime at twelve-hour intervals. This works in all real-world cases;
one can construct artificial time zones for which this fails.
