I am trying to figure out what causes this extra delay during these hours but i cannot find anything. I tried to check the crons to see if there is something automatic that runs during these hours that is causing the delay but i dont think my answer is there.
What makes you think the answer is not in the crontabs? (The question is meant serious, what haveyou done to come to that conclusion?)
You might want to start with the basic tool for all things performance: vmstat. Use
and analyse the log. See if there is any significant difference between the first 5-6 minutes of an hour and the rest of the time. See if there is a difference between the first 5-6 minutes of the hour on server3 and the other two servers.

tztab - time zone adjustment table for date and ctime()
DESCRIPTION
The file describes the differences between Coordinated Universal Time (UTC) and local time. Several local areas can be represented simul-
taneously with historical detail.
The file consists of one or more time zone adjustment entries. The first line of the entry contains a unique string that may match the
value of the string in the user's environment. The format is where is the time zone name or abbreviation, diff is the difference in hours
from UTC, and is the name or abbreviation of the "Daylight Savings" time zone. Fractional values of diff are expressed in minutes preceded
by a colon. Each such string will start with an alphabetic character.
The second and subsequent lines of each entry details the time zone adjustments for that time zone. The lines contain seven fields each.
The first six fields specify the first minute in which the time zone adjustment, specified in the seventh field, applies. The fields are
separated by spaces or tabs. The first six are integer patterns that specify the minute (0-59), hour (0-23), day of the month (1-31),
month of the year (1-12), year (1970-2038), and day of the week (0-6, with 0=Sunday). The minute, hour, and month of the year must contain
a number in the (respective) range indicated above. The day of the month, year, and day of the week can contain a number as above or two
numbers separated by a minus (indicating an inclusive range). Either the day of the month or the day of the week field must be a range,
the other must be simple number.
The seventh field is a string that describes the time zone adjustment in its simplest form: where is an alphabetic string giving the time
zone name or abbreviation, and diff is the difference in hours from UTC. must match either the field or the field in the first line of the
time zone adjustment entry. Any fractional diff is shown in minutes.
Comments begin with a in the first column, and include all characters up to a newline. Comments are ignored.

EXAMPLES
The time zone adjustment table for the Eastern Time Zone in the United States is:
Normally (as indicated in the first line) Eastern Standard Time is five hours earlier than UTC. During Daylight Savings time, it changes
to a 4 hour difference. The first time Daylight Savings Time took effect (second line) was on January 6, 1974 at 3:00 a.m., EDT. Note
that the minute before was 1:59 a.m., EST. The change back to standard time took effect (sixth line) on the last Sunday in November of the
same year. At that point, the time went from 1:59 a.m., EDT to 1:00 a.m., EST. The transition to Daylight Savings Time since then has
gone from the last Sunday in February (third line) to the last Sunday in April (fourth line) to the first Sunday in April (fifth line).
The return to standard time for the same period has remained at the last Sunday in October (seventh line).
