You can't disregard the difference of running in Cygwin. It's still subject to all Windows limitations, bugs, and idiosyncrasies. It's not UNIX, just a UNIX porting tool.
You should always explain what your OS is from the first anyway, UNIX or not.
Where does the date come from? The current time, or the file's modification time, or what?

rtc(1M) System Administration Commands rtc(1M)
NAME
rtc - provide all real-time clock and GMT-lag management
SYNOPSIS
/usr/sbin/rtc [-c] [-z zone-name]
DESCRIPTION
On x86 systems, the rtc command reconciles the difference in the way that time is established between UNIX and MS-DOS systems. UNIX systems
utilize Greenwich Mean Time (GMT), while MS-DOS systems utilize local time.
Without arguments, rtc displays the currently configured time zone string. The currently configured time zone string is based on what was
last recorded by rtc-z zone-name.
The rtc command is not normally run from a shell prompt; it is generally invoked by the system. Commands such as date(1) and rdate(1M),
which are used to set the time on a system, invoke /usr/sbin/rtc -c to ensure that daylight savings time (DST) is corrected for properly.
OPTIONS
-c This option checks for DST and makes corrections if necessary. It is normally run once a day by a cron job.
If there is no RTC time zone or /etc/rtc_config file, this option will do nothing.
-z zone-name This option, which is normally run by the system at software installation time, is used to specify the time zone in which
the RTC is to be maintained. It updates the configuration file /etc/rtc_config with the name of the specified zone and the
current GMT lag for that zone. If there is an existing rtc_config file, this command will update it. If not, this command
will create it.
FILES
/etc/rtc_config The data file used to record the time zone and GMT lag. This file is completely managed by /usr/sbin/rtc, and it is
read by the kernel.
